Then Jesus spoke to them again, saying, "I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life." Book of John 8:12
"I am the door. If anyone enters by Me, he will be saved, and will go in and out and find pasture."Book of John 10:9
Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me." Book of John 14:6
God the Father is the Israelite's only Savior.
“You are My witnesses,” declares the LORD, “and My servant whom I have chosen, so that you may consider and believe Me and understand that I am He. Before Me, no god was formed, and after Me none will come. 11
I, yes I, am the LORD, and there is no Savior but Me. 12 I alone decreed and saved and proclaimed—
I, and not some foreign god among you. So you are My witnesses,” declares the LORD, “that I am God. " The Book of Isaiah 43:10
