Bible Verses About Unity of God: His being the only Saviour

Tell ye and bring them, and let them take counsell together, who hath declared this from the beginning? or hath tolde it of olde? Haue not I the Lord? and there is none other God beside me, a iust God, and a Sauiour: there is none beside me.

Looke vnto me, and ye shall be saued: all the endes of the earth shall be saued: for I am God, and there is none other.
