By faith Abraham, etc. He comes now to Abraham, who is the chief father of God's church on earth, and in whose name the Jews gloried, as though by the distinction of being the holy race of Abraham alone, they were removed from the common order of men. But he now reminds them of what they ought to possess as the main thing, that they might be counted among his children. He therefore calls their attention to faith, for Abraham himself had no excellency which did not proceed from faith. He first teaches us that faith was the cause why he immediately obeyed God when he was commanded to remove from his own country; and then that through the same faith it was that he went on without wavering, according to what he was called to do even to the end. By these two things, -- his promptness in obeying, and his perseverance, was Abraham's faith most clearly proved. When he was called, etc. The old Latin translator and Erasmus apply this to his name, which is extremely tame and frigid. On the contrary, I refer it to the oracle by which he was called from his own country. He indeed did in this way undergo a voluntary exile, while yet he did nothing but by God's command; and no doubt it is one of the chief things which belong to faith, not to move a step except God's word shows us the way, and as a lantern gives us light, according to what David says. (Psalm 119:105.) Let us then learn that it is a thing to be observed through life, that we are to undertake nothing to which God does not call us. To go out into a place, [1] etc. To the command was added a promise, that God would give him a land for an inheritance. This promise he immediately embraced, and hastened as though he was sent to take possession of this land. It is a no ordinary trial of faith to give up what we have in hand, in order to seek what is afar off, and unknown to us. For when God commanded him to leave his own country, he did not point out the place where he intended him to live, but left him in suspense and perplexity of mind: "go", he said, "into the place that I will show thee." (Genesis 12:1.) Why did he defer to point out the place, except that his faith might be more and more exercised? Besides, the love of his native land might not only have retarded the alacrity of Abraham, but also held him so bound to it, so as not to quit his home. His faith then was not of an ordinary kind, which thus broke through all hindrances and carried him where the Lord called him to go.

1 - This is differently connected by Calvin, his version is "by faith Abraham, when he was called, obeyed, so that he went forth," etc. Bloomfield by supposing oste understood before exelthein, seems to be of the same opinion. Beza renders the verb by a gerund, "abiendo," by departing. This construction is more agreeable to the location of the words; the other introduces an unnatural transposition. Besides, the idea is somewhat different. There are thus two things in the verse stated more directly, as evidences and proofs of faith, -- his departure from his own country, and his ignorance as to the country where he was going. His faith was such that he obeyed, so as to leave his own country, and also to go to a country, of which he knew nothing. -- Ed

By faith Abraham - There is no difficulty in determining that Abraham was influenced by faith in God. The case is even stronger than that of Noah, for it is expressly declared, Genesis 15:6, "And he believed in the Lord; and he counted it to him for righteousness." Compare notes, Romans 4:1-5. In the illustrations of the power of faith in this chapter, the apostle appeals to two instances in which it was exhibited by Abraham, "the father of the faithful." Each of these required confidence in God of extraordinary strength, and each of them demanded a special and honorable mention. The first was that when he left his own country to go to a distant land of strangers (Genesis 15:8-10); the other when he showed his readiness to sacrifice his own son in obedience to the will of God, Hebrews 11:17-19.
When he was called - Genesis 12:1, "Now the Lord had said unto Abraham, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will show thee."
Into a place which he should after receive for an inheritance, obeyed - To Palestine, or the land of Canaan, though that was not indicated at the time.
And he went out, not knowing whither he went - Genesis 12:4. Abraham at that time took with him Sarai, and Lot the son of his brother, and "the souls that they had gotten in Haran." Terah, the father of Abraham, started on the journey with them, but died in Haran; Genesis 11:31-32. The original call was made to Abraham, Genesis 12:1; Acts 7:2-3, but he appears to have induced his father and his nephew to accompany him. At this time he had no children Genesis 11:30, though it seems probable that Lot had; Genesis 12:5. Some, however, understand the expression in Genesis 12:5, "and the souls they had gotten in Haran," as referring to the servants or domestics that they had in various ways procured, and to the fact that Abraham and Lot gradually drew around them a train of dependents and followers who were disposed to unite with them, and accompany them wherever they went. The Chaldee Paraphrast; understands it of the proselytes which Abraham had made there - "All the souls which he had subdued unto the law." When it is said that Abraham "went out, not knowing whither he went," it must be understood as meaning that he was ignorant to what country he would in fact be led. If it be supposed that he had some general intimation of the nature of that country, arid of the direction in which it was situated, yet it must be remembered that the knowledge of geography was then exceedingly imperfect; that this was a distant country; that it lay beyond a pathless desert, and that probably no traveler had ever come from that land to apprize him what it was. All this serves to show what was the strength of the faith of Abraham.

Abraham, when he was called - See on Genesis 12:1-4 (note).
Not knowing whither he went - Therefore his obedience was the fullest proof of his faith in God, and his faith was an implicit faith; he obeyed, and went out from his own country, having no prospect of any good or success but what his implicit faith led him to expect from God, as the rewarder of them that diligently seek him. In all the preceding cases, and in all that follow, the apostle keeps this maxim fully in view.

By faith, Abraham, when he was called,.... The Alexandrian copy and the Vulgate Latin version read, "by faith he who was called Abraham"; but this call is not to be understood of his name; for though his first name Abram might be given him, in the faith of his being a great man, and his second name Abraham, when he himself was a believer; yet this change was made some years after the call referred to; which is that in Genesis 12:1 when he was called out of his own country, kindred, and father's house; which was an emblem of the call of God's people out from among the men of the world, and from their friends, relations, and acquaintance, and even out of themselves; and as Abraham was called from "Ur" of the Chaldees, so they from darkness, bondage, idolatry, and communion with wicked men; that, as he, they might not perish with idolaters, being chosen vessels, and for whom God has peculiar blessings in store: and so the grace of God is seen in calling them, without any respect to their deserts, as in calling Abraham: and the care and goodness of God may be observed, in raising up fit instruments to propagate his cause and interest. Now Abraham, being called
to go out into a place; from Ur of the Chaldees, to the land of Canna;
which he should afterwards receive for an inheritance; not in his own person, but in his seed and posterity, unless after the resurrection, in the New Jerusalem church state, and which inheritance was typical of heaven;
obeyed the divine call; and which was a fruit and evidence of his faith, and may he called the obedience of faith:
and he went out, not knowing whither he went: for though he went forth to go into the land of Canaan, and into the land of Canaan he came, Genesis 12:5, yet, when God called him to go forth, and he prepared to obey his call, he knew not what land he was to go into; for it is only said, Genesis 12:1,
unto a land that I will show thee: upon which words a Jewish commentator (r) has this note;
"he (God) did not immediately make known the land unto him, that so it might be lovely in his eyes;''
and it is, elsewhere, said by the Jews (s), that Abraham
"came from Aspamia (i.e. Mesopotamia), and its companions, , "and he knew not where" he was, as a man that is in the dark;''
all which agrees with our apostle: and, from hence, it may be observed, that God sometimes leads his people in ways they have not known, though they are known to him, and are always right; and that it is the property of faith to follow God, when it cannot see its way; and a great mercy it is to have God for a guide. This also shows, that Abraham's faith agrees with the apostle's definition of it, Hebrews 11:1.

We are often called to leave worldly connexions, interests, and comforts. If heirs of Abraham's faith, we shall obey and go forth, though not knowing what may befall us; and we shall be found in the way of duty, looking for the performance of God's promises. The trial of Abraham's faith was, that he simply and fully obeyed the call of God. Sarah received the promise as the promise of God; being convinced of that, she truly judged that he both could and would perform it. Many, who have a part in the promises, do not soon receive the things promised. Faith can lay hold of blessings at a great distance; can make them present; can love them and rejoice in them, though strangers; as saints, whose home is heaven; as pilgrims, travelling toward their home. By faith, they overcome the terrors of death, and bid a cheerful farewell to this world, and to all the comforts and crosses of it. And those once truly and savingly called out of a sinful state, have no mind to return into it. All true believers desire the heavenly inheritance; and the stronger faith is, the more fervent those desires will be. Notwithstanding their meanness by nature, their vileness by sin, and the poverty of their outward condition, God is not ashamed to be called the God of all true believers; such is his mercy, such is his love to them. Let them never be ashamed of being called his people, nor of any of those who are truly so, how much soever despised in the world. Above all, let them take care that they are not a shame and reproach to their God. The greatest trial and act of faith upon record is, Abraham's offering up Isaac, Genesis 22:2. There, every word shows a trial. It is our duty to reason down our doubts and fears, by looking, as Abraham did, to the Almighty power of God. The best way to enjoy our comforts is, to give them up to God; he will then again give them as shall be the best for us. Let us look how far our faith has caused the like obedience, when we have been called to lesser acts of self-denial, or to make smaller sacrifices to our duty. Have we given up what was called for, fully believing that the Lord would make up all our losses, and even bless us by the most afflicting dispensations?

From the antediluvian saints he passes to the patriarchs of Israel, to whom "the promises" belonged.
called--by God (Genesis 12:1). The oldest manuscripts and Vulgate read, "He that was called Abraham," his name being changed from Abram to Abraham, on the occasion of God's making with him and his seed a covenant sealed by circumcision, many years after his call out of Ur. "By faith, he who was (afterwards) called Abraham (father of nations, Genesis 17:5, in order to become which was the design of God's bringing him out of Ur) obeyed (the command of God: to be understood in this reading), so as to go out," &c.
which he should after receive--He had not fully received even this promise when he went out, for it was not explicitly given him till he had reached Canaan (Genesis 12:1, Genesis 12:6-7). When the promise of the land was given him the Canaanite was still in the land, and himself a stranger; it is in the new heaven and new earth that he shall receive his personal inheritance promised him; so believers sojourn on earth as strangers, while the ungodly and Satan lord it over the earth; but at Christ's coming that same earth which was the scene of the believer's conflict shall be the inheritance of Christ and His saints.

By faith Abraham. See Genesis 11:31; Genesis 12:1-4. While in Ur of the Chaldees he was commanded to go where he should be led. In obedience to this call he obeyed through faith, a striking example of the action of faith.
By faith he sojourned in the land of promise. He was a stranger in the land promised to him and his seed, dwelling as did Isaac and Jacob, in tents, yet trusting the promise of God.
Heirs . . . of the same promise. See Genesis 26:3-4; Genesis 27:4, Genesis 27:13-14.
For he looked for a city which hath foundations. Not only for a permanent home for his seed in Canaan, but for a home above in the eternal city, the New Jerusalem.
Builder and maker. Architect and maker. God not only projected the plans of the eternal city but has executed them.
Faith also Sarah. See Genesis 17:15-21; Genesis 18:11-14; Genesis 21:1-2. Far beyond the years of child bearing, yet by faith she was give natural strength to bear the child of promise. She was about ninety years old.
Therefore sprang there even of one, and him as good as dead. From an old man, a hundred years old, whose reproductive powers were dead, a people.
As the stars of the sky in multitude. See Deuteronomy 1:10. These figures are used to express a vast multitude.
