"I AM WHO I AM" - Exodus 3:14.

"I am the Alpha [beginning] and the Omega [end]" - Revelation 1:8

God the Father is the completely self-sufficient, eternal being who is who He says He is without wavering, without ever changing. He has no need or desire to change, for if He did He'd cease to be who He is. This is why He is the ONLY ONE whom we can rely on for our Salvation through His Son, Jesus, who was made sacrifice and defeated death to pave the way for us to experience eternal life. Praise be to the Father!
