Concise Bible Dictionary:

This title is in the Old Testament applied to Jehovah. The term in itself implies that some oppression exists or some danger impends from which salvation is needed. God says, “All flesh shall know that I Jehovah am thy Saviour and thy Redeemer, the Mighty One of Jacob” (Isa. 49:26; Isa. 60:16). In the New Testament man is plainly declared to be lost, and the title “Saviour” is applied both to God and to Christ. “The Father sent the Son to be the Saviour of the world” (1 John 4:14); and the very name of Jesus conveys the thought of a Saviour. His becoming this involved His meeting vicariously the question of sin and sins, which He did on the cross. The expression occurs in Paul’s later epistles of “God our Saviour,” or “our Saviour-God,” indicating the attitude which God occupies towards all men. How gladly all His saints say, “To the only wise God our Saviour be glory and majesty, dominion and power, both now and ever. Amen.” God is also declared to be “the Savior of all men” in a providential sense, and men probably little know how much they are indebted to His preserving care (1 Tim. 4:10). See SALVATION.
