Isaiah’s prophetic book is teeming with revelations about God. Perhaps one of the clearest revelations about God is the declaration that He alone is God and Savior. Chapters forty through forty-nine make statements that there is only one God, and He alone is the Savior of humanity. He is the first and the last (Isa. 41:3;44:6). He is the Holy One (Isa. 43:3). There is no other God besides Him (Isa. 43:10-11; 44:6). He alone created the heavens and the earth (Isa. 44:24;45:12,18). He alone is God and there is not another (Isa. 54:5-6). God alone is the Savior, and there is none else (Isa. 45:21-22; 49:26).
God is emphatically declaring that He alone is God. He alone is the Creator of the heavens and the earth. By Himself He will save humanity from their sin. All of this is to say, “I am the Lord: that is my name: and my glory I will not give to another, neither my praise to graven images” (Isa. 42:8). No one else is God. No one else can claim to be Creator. No one else can claim to be Savior. Therefore, He will not share His glory with anything or anyone else.
Why is this important? Because we are quickly approaching Isaiah’s prophecy concerning God’s revealed plan to save humanity from their sin (Isa. 52-53). God wasn’t going to send someone else to do His work. Rather, “And I looked, and there was none to help; and I wondered that there was none to uphold: therefore mine own arm brought salvation unto me; and my fury, it upheld me” (Isa. 63:5).
In light of Isaiah’s book, when we reach the New Testament we gain a clearer picture. God is called Savior (1 Tim. 1:1; 2:3; 4:10; Titus 1:3; 2:10; 3:4; Jude 1:25). Jesus is called Savior (2 Tim. 1:10; Titus 1:4; 2:13; 3:6; 2 Pt. 1:1; 2:20). God is called the Creator (Eph. 3:9; Rev. 4:11). Jesus is called the Creator (Col. 1:16; Heb.1:2). Finally, Jesus is declared to be Lord and God (Jn. 20:28).
These aren’t contradictory statements. Rather, Jesus Christ is God in flesh (Jn. 1:1-3; 14). Jesus isn’t another God, He is God! Jesus isn’t another Lord, He is Lord! Jesus isn’t a created lesser being than God, He is the Creator-God come in flesh! Jesus could do only what God could do, because He was God.
