This Jesus is the stone that was rejected by you, the builders, which has become the cornerstone. And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved (Acts 4:11-12).
It is interesting that the Old Testament records a passage written about 700 years prior to Jesus in which we are taught that the LORD (literally Yahweh) is our only Savior:
You are my witnesses,” declares the LORD, “and my servant whom I have chosen, that you may know and believe me and understand that I am he. Before me no god was formed, nor shall there be any after me. I, I am the LORD, and besides me there is no savior (Isaiah 43:10-11).
Sine we know that Jesus is also fully God, these passages are easy to harmonize. It is also a great reminder that God’s ultimate plan of redemption for his people has never changed. The depth of the revelation culminated in the coming of Christ Jesus, but the plan was clear from the beginning.
