But when it pleased God, who separated me from my mother's womb, and called me by his grace,

But when God, who set me apart even from my mother's womb, and called me by his grace,

and when God was well pleased, having separated me from the womb of my mother, and having called me through His grace,

But when He who set me apart even from my birth, and called me by His grace,

But when it was the good pleasure of God, by whom I was marked out even from my mother's body, through his grace,

But when God, who had set me apart even before my birth, and who called me by his love,

At postquam placuit Deo, qui me segregaverat ab utero matris meae, et vocavit per gratiam suam,

But after that it pleased God. This is the second part of the narrative, and relates to his miraculous conversion. He tells us, first, that he had been called by the grace of God to preach Christ among the Gentiles; and, next, that as soon as he had been called, without consulting the apostles, he unhesitatingly proceeded to the performance of the work, which, he felt assured, had been enjoined upon him by the appointment of God. In the construction of the words, Erasmus differs from the Vulgate. He connects them in the following manner: "When it pleased God that I should preach Christ among the Gentiles, who called me for this purpose that he might reveal him by me." But I prefer the old translation; for Christ had been revealed to Paul before he received a command to preach. Admitting that Erasmus were right in translating en emoi, by me, still the clause, that I might preach, is added for the purpose of describing the kind of revelation. Paul's reasoning does not, at first sight, appear so strong; for although, when he had been converted to Christianity, he instantly, and without consulting the apostles, entered into the office of preaching the gospel, it does not thence follow that he had been appointed to that office by the revelation of Christ. But the arguments which he employs are various, and, when they are all collected, will be found sufficiently strong to establish his conclusion. He argues, first, that he had been called by the grace of God; next, that his apostleship had been acknowledged by the other apostles; and the other arguments follow. Let the reader, therefore, remember to read the whole narrative together, and to draw the inference, not from single parts, but from the whole. Who had separated me. This separation was the purpose of God, by which Paul was appointed to the apostolic office, before he knew that he was born. The calling followed afterwards at the proper time, when the Lord made known his will concerning him, and commanded him to proceed to the work. God had, no doubt, decreed, before the foundation of the world, what he would do with regard to every one of us, and had assigned to every one, by his secret counsel, his respective place. But the sacred writers frequently introduce those three steps: the eternal predestination of God, the destination from the womb, and the calling, which is the effect and accomplishment of both. The word of the Lord which came to Jeremiah, though expressed a little differently from this passage, has entirely the same meaning. "Before I formed thee in the belly, I knew thee; and before thou camest forth from the womb I sanctified thee; a prophet to the nations have I made thee." (Jeremiah 1:5.) Before they even existed, Jeremiah had been set apart to the office of a prophet, and Paul to that of an apostle; but he is said to separate us from the womb, because the design of our being sent into the world is, that he may accomplish, in us, what he has decreed. The calling is delayed till its proper time, when God has prepared us for the office which he commands us to undertake. Paul's words may therefore be read thus: "When it pleased God to reveal his Son, by me, who called me, as he had formerly separated me." He intended to assert, that his calling depends on the secret election of God; and that he was ordained an apostle, not because by his own industry he had fitted himself for undertaking so high an office, or because God had accounted him worthy of having it bestowed upon him, but because, before he was born, he had been set apart by the secret purpose of God. Thus, in his usual manner, he traces his calling to the good pleasure of God. This deserves our careful attention; for it shows us that we owe it to the goodness of God, not only that we have been elected and adopted to everlasting life, but that he deigns to make use of our services, who would otherwise have been altogether useless, and that he assigns to us a lawful calling, in which we may be employed. What had Paul, before he was born, to entitle him to so high an honor? In like manner we ought to believe, that it is entirely the gift of God, and not obtained by our own industry, that we have been called to govern the Church. The subtle distinctions into which some commentators have entered in explaining the word separated, are altogether foreign to the subject. God is said to separate us, not because he bestows any peculiar disposition of mind which distinguishes us from others, but because he appoints us by his own purpose [1] . Although the apostle had most explicitly attributed his calling to the free grace of God, when he pronounced that voluntary separation from the womb to be the origin of it, yet he repeats the direct statement, both that, by his commendation of Divine grace, he may take away all grounds of boasting, and that he may testify his own gratitude to God. On this subject he is wont freely to expatiate, even when he has no controversy with the false apostles.

Footnotes

1 - "Quand par son conseil il nous destine a quelque chose." "When he appoints us to any thing by his purpose."

But when it pleased God - Paul traced all his hopes of eternal life, and all the good influences which had ever borne upon his mind, to God.
Who separated me - That is, who destined me; or who purposed from my very birth that I should be a preacher and an apostle. The meaning is, that God had in his secret purposes set him apart to be an apostle. It does not mean that he had actually called him in his infancy to the work, for this was not so, but that he designed him to be an important instrument in his hands in spreading the true religion. Jeremiah Jeremiah 1:5 was thus set apart, and John the Baptist was thus early designated for the work which they afterward performed. It follows from this:
(1) That God often, if not always, has purposes in regard to people from their very birth. He designs them for some important field of labor, and endows them at their creation with talents adapted to that.
(2) it does not follow that because a young man has gone far astray; and has become even a blasphemer and a persecutor, that God has not destined him to some important and holy work in his service. How many people have been called, like Paul, and Newton, and Bunyan, and Augustine, from a life of sin to the service of God.
(3) God is often training up people in a remarkable manner for future usefulness. His eye is upon them, and He watches over them, until the time comes for their conversion. His providence was concerned in the education and training of Paul. It was by the divine intention with reference to his future work that he had so many opportunities of education, and was so well acquainted with the "traditions" of that religion which he was yet to demonstrate to be unfounded and false. He gave him the opportunity to cultivate his mind, and prepare to grapple with the Jew in argument, and show him how unfounded were his hopes. So it is often now. He gives to a young man an opportunity of a finished education. Perhaps he suffers him to fall into the snares of infidelity, and to become familiar with the arguments of sceptics, that he may thus be better prepared to meet their sophisms and to enter into their feelings. God's eye is upon them in their wanderings, and they are often allowed to wander far; to range the fields of science; to become distinguished as scholars, as Paul was; until the time comes for their conversion, and then, in accordance with the purpose which set them apart from the world, God converts them, and consecrates all their talents and attainments to His service.
(4) we should never despair of a young man who has wandered far from God. If he has risen high in attainments; if his whole aim is ambition; or if he has become an infidel, still we are not to despair of him. It is still possible that God "separated" that talent to his service from his very birth, and that God still means to call it all to His service. How easy it was to convert Saul of Tarsus when the proper period arrived. So it is of the now unconverted and unconsecrated, but cultivated talent among the young men of our land. Far as they may have wandered from God and virtue, yet much of that talent has been devoted to Him in baptism, and by parental purposes and prayers; and, it may be - as is morally certain from the history of the past - that much of it is consecrated also by the divine purpose and intention for the noble cause of virtue and pure religion. In that now apparently wasted talent; in that learning now apparently devoted to other aims and ends, there is much that may still adorn the cause of virtue and religion; and how fervently we should pray that it may be "called" by the grace of God and actually devoted to His service.
And called me by his grace - On the way to Damascus. It was special grace, because he was then engaged in bitterly opposing Him and His cause.

Who separated me from my mother's womb - Him whom I acknowledge as the God of nature and the God of grace; who preserved me by his providence when I was a helpless infant, and saved me by his grace when I was an adult persecutor. For some useful remarks on these passages see the introduction, sec. 2.

But when it pleased God, who (l) separated me from my mother's womb, and called [me] by his grace,
(l) He speaks of God's everlasting predestination, by which he appointed him to be an apostle, of which he makes three distinctions: the everlasting council of God, his appointing from his mother's womb, and his calling. And we see that there is no mention at all of foreseen works.

But when it pleased God,.... Here begins his account of his conversion, and call to the ministry; all which he ascribes entirely to the sovereign good pleasure, and free grace of God:
who separated me from my mother's womb. By his "mother" is meant, not in an improper and figurative sense, the Jewish church, or the old synagogue, the mother of all its members; the Jerusalem which then was, and was in bondage with her children; from which bondage, blindness, ignorance, superstition and bigotry, he was delivered, when called by grace: nor the church at Antioch, which is never called a mother church; and though he was by that church, with Barnabas, separated for the work of the ministry, yet not from it: but by his "mother", without a figure is meant, his real natural mother, whose name is said to be Theocrita; and this separation from her womb is to be understood either of that distinction made of him in Providence, as soon as born; which not only took him, and safely brought him out of his mother's womb, but ever since took special care of him, and saved and preserved him to be called; for all the chosen vessels of salvation are distinguished from others, in a providential way; they are more under the special care of Providence than others are, even whilst in a state of unregeneracy; God's eye of Providence is upon them, his heart is towards them, he waits upon them to be gracious to them, and many are the remarkable appearances of Providence for them; see Psalm 22:9. Or rather this designs divine predestination, which is a separation, a setting apart of persons, for such and such purposes, as here of the apostle; and the eternity of it, it being very early done, from his mother's womb; whilst he was in it, before he was born, and had done either good or evil; from the beginning of time, from the foundation of the world, and before it, even from eternity: all which phrases express the same thing, and intend either his predestination to grace and glory, to holiness and happiness, to sanctification of the Spirit, and belief of the truth, and to the obtaining the glory of our Lord Jesus Christ; or his predestination to apostleship, to the work of the ministry, to the Gospel of Christ, to which he was separated in eternity, and in time; reference seems to be had to Jeremiah 1:5 or indeed both, and his separation or predestination to both was owing to the sovereign will and good pleasure of God, as was also his after call:
and called me by his grace; which follows upon separation, as it does on predestination, in Romans 8:30 and is to be interpreted either of his call at conversion, by powerful and efficacious grace; when he was called out of Jewish darkness, blindness, and ignorance, into Gospel light and knowledge; out of the bondage of sin, Satan, the law, and traditions of the fathers, into the liberty of Christ; from conversation with the men of the world, among whom before he had it, into the fellowship of Father, Son, and Spirit, angels and saints; out of himself, and off of a dependence on his own righteousness, to trust in Christ: in a word, he was called into the grace of Christ here, into a participation of all the blessings of grace, and to eternal glory by him hereafter; which call was not of men, but of God, as the efficient cause of it; and by his grace, as the moving and procuring cause of it, and without the use of means, the word, which is the ordinary way in which God calls his people; so that it is plain his first light into the Gospel, was not of man, nor so much as by the means of man: or this call may respect his call to the ministry, which was at the same time he was effectually called by grace; and which also was not of man, nor of himself; he did not thrust himself into this work, but God called him; and that of his mere grace and good will, without any respect to any merits, deserts, or qualifications in him.

St. Paul was wonderfully brought to the knowledge and faith of Christ. All who are savingly converted, are called by the grace of God; their conversion is wrought by his power and grace working in them. It will but little avail us to have Christ revealed to us, if he is not also revealed in us. He instantly prepared to obey, without hesitating as to his worldly interest, credit, ease, or life itself. And what matter of thanksgiving and joy is it to the churches of Christ, when they hear of such instances to the praise of the glory of his grace, whether they have ever seen them or not! They glorify God for his power and mercy in saving such persons, and for all the service to his people and cause that is done, and may be further expected from them.

separated--"set me apart": in the purposes of His electing love (compare Acts 9:15; Acts 22:14), in order to show in me His "pleasure," which is the farthest point that any can reach in inquiring the causes of his salvation. The actual "separating" or "setting apart" to the work marked out for him, is mentioned in Acts 13:2; Romans 1:1. There is an allusion, perhaps, in the way of contrast, to the derivation of Pharisee from Hebrew, "pharash," "separated." I was once a so-called Pharisee or Separatist, but God had separated me to something far better.
from . . . womb--Thus merit in me was out of the question, in assigning causes for His call from Acts 9:11. Grace is the sole cause (Psalm 22:9; Psalm 71:6; Isaiah 49:1, Isaiah 49:5; Jeremiah 1:5; Luke 1:15).
called me--on the way to Damascus (Acts 9:3-8).

But when it pleased God. The language that follows implies that, like Moses, John the Baptist, Isaiah (Isaiah 49:1), and Jeremiah (Jeremiah 1:5), Paul was destined to his work from birth.
To reveal his Son in me. It was one thing to call him, as was done on the way to Damascus; another to reveal Christ to him. This was needful that he should be a witness of the resurrection to the Gentiles.
I conferred not with flesh and blood. He did not go to men to learn more, or for counsel.
Neither went I . . . to them which were apostles. He did not seek those who were apostles before him at Jerusalem to be taught.
I went into Arabia. This is the only place where this fact is mentioned. Like Moses and Elijah, he spent a season, perhaps for reflection, communion with God, and preparation, amid the Arabian solitudes. He then returned to Damascus. Here he probably did his first preaching (Acts 9:20-22). Arabia lay south and east of Palestine, extending to the vicinity of Damascus.

But when it pleased God - He ascribes nothing to his own merits, endeavours, or sincerity. Who separated me from my mother's womb - Set me apart for an apostle, as he did Jeremiah for a prophet. Jeremiah 1:5. Such an unconditional predestination as this may consist, both with God's justice and mercy. And called me by his grace - By his free and almighty love, to be both a Christian and an apostle.
