Isaiah 45:20

"Assemble yourselves and come; draw near together, ye that escaped of the nations: they have no knowledge that carry the wood of their graven image, and pray unto a god that cannot save. Declare ye, and bring it forth; yea, let them take counsel together: who hath showed this from ancient time? who hath declared it of old? have not I, Jehovah? and there is no God else besides me, a just God and a Saviour; there is none besides me. Look unto me and be ye saved, all the ends of the earth; for I am God, and there is none else. By myself have I sworn, the word is gone forth from my mouth in righteousness, and shall not return, that unto me every knee shall bow, every tongue swear. Only in Jehovah, it is said of me, is righteousness and strength; even to him shall men come; and all they that were incensed against him shall be put to shame. In Jehovah shall all the seed of Israel be justified, and shall glory."

The Old Israel is hardly in this passage at all, for it is addressed "unto them that escaped of the nations," to all of the redeemed of the whole earth, as indicated in Isaiah 45:22.

Note also that the last two verses here have the expressions "Only in Jehovah," and "In Jehovah shall all the seed of Israel be blessed," these being the exact parallels of the great Pauline conception of salvation "in the Lord," "in Christ," "in him," "in the Beloved," and equivalent expressions, which are found "one hundred-sixty nine times in Paul's New Testament writings."[20]

There is a widespread misunderstanding of what is meant by Isaiah 45:23. Wardle thought that the meaning is, "Every man shall swear allegiance to God";[21] However, the New Testament usage of this passage shows more clearly what the Spirit says. "At the name of Jesus every knee shall bow, of things in heaven, and things in earth, and things under the earth, and every tongue shall confess that Jesus is Lord to the glory of God the Father" (Philippians 2:10,11). Also, in Revelation 6:14-17, we are given a more intimate glimpse of the nature of that confession which even the most wicked of men shall eventually make.

This passage also teaches that "no Israelite shall be saved apart from his union with Jehovah and "in Jehovah," a status that has never been attained by any person who ever lived apart from his being baptized "into Christ" (Romans 6:3-5; 1 Corinthians 12:13; and Galatians 3:27); because Christ is indeed "God come in the flesh." He is actually called "God," no less than ten times in the Greek New Testament (John 1:1,18; 20:28; Acts 20:28; Hebrews 1:8; Philippians 2:6; Romans 9:5; 1 Timothy 3:16; Titus 2:13; and 1 John 5:20, etc.). Thus, in these verses the great climax of Isaiah's prophecies is fully realized in the glorious salvation to all men in the New Covenant. "The religion of Israel is to become the religion of all mankind; and this anticipation finds its fulfillment in the Christian dispensation,"[22] and this is proved by Paul's application of these verses to Christ in Philippians 2:10,11, and in Romans 14:11.

We should not overlook the fact that this passage "also abolishes the last vestiges of nationalism in the true religion."[23] It is also inherent in the same truth that the last vestiges of racism have also been forever removed in the true religion. No man will ever be saved on account of his race, or denied salvation on the basis of it. "Preach the Gospel to the whole creation; he that believeth and is baptized shall be saved." (Mark 16:16).
