“The Scripture, foreseeing that God would justify the Gentiles by faith, preached the Gospel beforehand unto Abraham.” This verse will bear much reading. An understanding of it will guard one against many errors. And it is not difficult to understand; simply hold to what it says, and you have it.
(a) For one thing, the verse shows us that the Gospel was preached at least as early as the days of Abraham.
(b) It was God Himself who preached it; therefore, it was the true and only Gospel.
(c) It was the same Gospel that Paul preached; so that we have no other Gospel than that which Abraham had.
(d) The Gospel differs in no particular now from what it was in Abraham’s day; for his day was the day of Christ. John 8:56.
God requires just the same things now that He required then, and nothing more.
Moreover, the Gospel was then preached to the Gentiles, for Abraham was a Gentile, or, in other words, a heathen. He was brought up as a heathen, for “Terah, the father of Abraham,” “served other gods” (Joshua 24:2), and was a heathen till the Gospel was preached to him. So the preaching of the Gospel to the Gentiles was no new thing in the days of Peter and Paul. The Jewish nation was taken out from among the heathen, and it is only by the preaching of the Gospel to the heathen that Israel is built up and saved. See Acts 15:14-18; Rom. 11:25, 26. The very existence of the people Israel always was and still is a standing proof that God’s purpose is to save a people from among the Gentiles. It is in fulfilment of this purpose that Israel exists.
Thus we see that the apostle takes the Galatians, and us, back to the fountain-head,—to the place where God Himself preaches the Gospel to us Gentiles. No Gentile can hope to be saved in any other way or by any other gospel than that by which Abraham was saved.
Blessed with Abraham.
“So then they which be of faith are blessed with faithful Abraham.” Mark the close connection between this and the preceding verse. The Gospel was preached to Abraham in the words, “In thee shall all nations be blessed.” (It should be remembered, in passing, that the words “heathen,” or “Gentiles,” as in the Revised Version, and “nations,” in verse 8, come from the very same Greek word.) This blessing is the blessing of righteousness through Christ, as we learn from Acts 3:25, 26: “Ye are the children of the prophets, and of the covenant which God made with our fathers, saying unto Abraham, And in thy seed shall all the kindreds of the earth be blessed. Unto you first God, having raised up His Son Jesus, sent Him to bless you, in turning away every one of you from his iniquities.” Because God preached the Gospel to Abraham, saying, “In thee shall all the nations of the earth be blessed,” those who believe are blessed with the faithful Abraham. There is no blessing for any man except the blessing which Abraham received, and the Gospel preached to him is the only Gospel there is for any people under heaven; for besides the name of Jesus, in whom Abraham believed, “there is none other name under heaven given among men whereby we must be saved.” In Him “we have redemption through His blood, even the forgiveness of sins.” Col. 1:14. The forgiveness of sins carries with it all blessings.
