Because I am. This is the former reason why Paul, having subdued fear, must manfully and stoutly do his duty, because he hath God on his side. Whereto answereth the rejoicing of David, "If I shall walk in the midst of the shadow of death, I shall fear none ill: because thou art with me," (Psalm 23:4.) Again, "If tents be pitched about me," etc., (Psalm 27:3.) The question is, whether he did not perceive that God was present with him elsewhere, as he had had experience of his help in divers places. For the promise is general, "I am with you until the end of the world," (Matthew 28:20.) Neither is it lawful for us to mistrust so often as we obey his calling, but that he will be present with us. But it is an usual thing with the Lord to apply that unto certain kinds when the matter so requireth, which he hath promised to do in all affairs; and we know that when we come to the push, then are we most desirous of help. Moreover, these two members are joined together, "I am with thee, and no man shall hurt thee." For it falleth out sometimes that God doth help us, and yet doth he, to look to, suffer us to be oppressed, as he forsook not Paul even in the midst of death; and here he promiseth the peculiar defense of his hand, whereby he shall be preserved from the violence of his enemies. But the question is, whether Paul needed any such confirmation, who ought to have been willing to enter [undergo] all manner [of] dangers. For what if he had been to suffer death, should he therefore have fainted through fear? I answer, that if at any time God pronounce that his servants shall be safe for a time, that doth no whit hinder, but that they may prepare themselves to suffer death valiantly; but as we distinguish between profitable and necessary, so we must note that there be some promises, which, if the faithful want, they must needs faint and sink down; [1] and that other some are added when it is expedient so to be, which, though they be taken away, (because the grace of God doth nevertheless remain firm and sure,) the faith of the godly doth not fail. After this sort, Paul is commanded not to fear, because his enemies shall not touch him; and if so be he should have been oppressed even then with their violence, yet would he not have been afraid, but God would have his boldness and courage to increase even by this, because he should be without danger. If at any time the Lord bear with us so far forth, we are not to despise such a comfort of our infirmity. In the mean season, let this be sufficient for us to tread under foot all corrupt fear of the flesh, that so long as we fight under his banner we cannot be forsaken of him. And when it is said, "No man shall gainstand thee to do thee hurt," the Lord doth not mean that he shall be free from violence and tumult whom the Jews did afterward deadly invade; but his meaning is, that their attempts shall be frustrate, because the Lord had determined to deliver him out of their hands. Therefore, we must fight stoutly that we may win the field. [2] Because I have much people. The second reason why he should take a good heart is, because the Lord will raise up a great and populous church there, though it be to be doubted whether this member depend upon that which goeth next before; for the text will run fitly thus, Because the Lord determined by the hand of Paul to gather together a great church, he would not suffer the enemies to interrupt the course of his labors, as if he should have said, I will help thee, that thou mayest not fail my people whose minister I have appointed thee to be. I do willingly embrace this exposition, that divers reasons are not inferred which are to be read apart, but that they be so distinguished that they agree together. Furthermore, the Lord calleth those his people, who, though they might then for good causes be counted strangers, yet because they were written in the book of life, and were forthwith to be admitted into his family, they have this title given them not improperly. For we know that many sheep wander without the flock for a time, as the sheep have many wolves among them. Therefore whom the Lord determined shortly after to gather to himself, those doth he take for his people in respect of their future faith. But let us remember, that those are engrafted into the body of Christ who appertain unto the same by the eternal adoption of God; as it is written, "Thine they were and thou gavest them me" (John 17:6.)

Footnotes

1 - "Penitus," altogether.

2 - "Victoria," victory.

For I am with thee - I will attend, bless, and protect you. See the notes on Matthew 28:20.
No man shall set on thee - No one who shall rise up against thee will be able to hurt thee. His life was in God's hands, and he would preserve him in order that his people might be collected into the church.
For I have - Greek: there is to me; that is, I possess, or there belongs to me.
Much people - Many who should be regarded as his true friends, and who should be saved.
In this city - In that very city that was so voluptuous, so rich, so effeminate, and where there had been already so decided opposition shown to the gospel. This passage evidently means that God had a design or purpose to save many of that people, for it was given to Paul as an encouragement to him to labor there, evidently meaning that God would grant him success in his work. It cannot mean that the Lord meant to say that the great mass of the people, or that the moral and virtuous part, if there were any such, was then regarded as his people; but that he intended to convert many of those guilty and profligate Corinthians to himself, and to gather a people for his own service there. We may learn from this:
(1) That God has a purpose in regard to the salvation of sinners.
(2) that that purpose is so fixed in the mind of God that he can say that those in relation to whom it is formed are his.
(3) this is the ground of encouragement to the ministers of the gospel. Had God no purpose to save sinners, they could have no hope in their work.
(4) this plan may have reference to the most frivolous, the most guilty, and the most abandoned, and ministers should not be deterred by the amount or the degree of wickedness from attempting to save them.
(5) there may be more hope of success among a dissolute and profligate population, than among proud, cold, and skeptical philosophers. Paul had little success in philosophic Athens; he had great success in dissolute Corinth. There is often more hope of converting a man openly dissolute and abandoned, than one who prides himself on his philosophy, and is confident in his own wisdom.

No man shall set on thee - Και ουδεις επιθησεται σοι, No man shall be permitted to lay violent hands upon thee. It is very likely that the Jews had conspired his death; and his preservation was an act of the especial interposition of Divine Providence.
I have much people in this city - Εν τῃ πολει ταυτῃ, In this very city: there are many here who have not resisted my Spirit, and consequently are now under its teachings, and are ready to embrace my Gospel as soon as thou shalt declare it unto them.

For I am with thee,.... According to his promise, Matthew 28:20 not only to assist in the ministry of the word, to give light into it, and liberty to preach it, and success in it, but to keep and preserve him from being hurt by men:
and no man shall set on thee; attack thee, or lay hands on thee:
to hurt thee; to do any injury to thy person, to thy body, in any part of it: wicked men cannot strike a blow, or do the least damage to a servant of Christ without his permission; he can tie their hands, and restrain their rage.
For I have much people in this city; this wicked and luxurious city; there were many here who were yet in their sins, in a state of unregeneracy, whom God had chosen to be his people, and had taken into his covenant as such; were given to Christ as his peculiar people, and whom he had redeemed with his precious blood: they were his people both by gift and purchase, before they were called by grace; and because of this his interest in them, he will have his Gospel continued for the gathering them in to himself; for Christ will lose none of his, all shall come unto him: from all which it appears, that Christ has a people who are related to him, and he has an interest in, before they are effectually called by grace; for this refers not to the many Corinthians who had heard and believed, and were baptized, but to some that had not, and were yet to be called; not the Jews in this city, Christ's own nation, nor all the inhabitants of it who were in some sense Christ's people, being made and supported in their beings by him, are intended; but a special people among the Gentiles, the same with the other sheep Christ speaks of, John 10:16 not yet of his fold; a people beloved of God, chosen in Christ, given to him, and with whom a covenant was made in him, for whom Christ undertook, in whose name he acted, and for whom he received blessings and promises, as well as took the care and charge of their persons; for the sake of these he assumed human nature, and suffered and died; towards these his heart always is; his eye is upon them, and he knows them, and where they are; and therefore he will look them up and find them out, and they shall be brought to believe in him, and shall not perish, but have everlasting life: and it may be further observed, that Christ has "many" such, though they are but comparatively few, yet in themselves they are a great number; yea, he has sometimes many of these in the worst of places, and among the vilest of men; and for the sake of these, in order to select and separate them from the rest, is the Gospel preached and continued. The ministers of it are sent here and there, where such persons are, and there they are continued till they are gathered in; yea, on this account both the Gospel and its preachers are continued in the world; and even the world itself, for the sake of these, till they are brought in, and then it will be destroyed; and it may be also remarked, that for the encouragement of Gospel ministers, Christ promises his presence and protection, and which was fulfilled in the Apostle Paul at Corinth; who though he stayed there a year and six months, none were suffered to do him any injury; and when an insurrection was made within that time, yet the apostle escaped, and quietly departed elsewhere.

I have much people in this city--"whom in virtue of their election to eternal life He already designates as His" (compare Acts 13:48) [BAUMGARTEN].

I am with thee: therefore fear not all the learning, politeness, grandeur, or power of the inhabitants of this city. Speak and hold not thy peace - For thy labour shall not be in vain. For I have much people in this city - So he prophetically calls them that afterward believed.
