Salvation by no other God
The Incarnation, God becoming flesh. Salvation, that is his name. "The Lord has become my light and my salvation" (Psalm 27:1) Salvation cannot come any other way other than through God whose name is salvation. Men can offer their version of it, but they themselves are not what they offer. Only this God can offer salvation because that is what he is, salvation! "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved " (Acts 4:12).
