Muffled
Jesus in me
Jesus is not God the Father (or God Almighty or the Most High God) but I definitely don't think the indefinite article "a" is needed in this verse. "And the word was God" is entirely acceptable. Jesus refers to himself as "God" in the New Testament when He describes His agony in Gethsemane.
I believe God is one, so He is Jesus, the Father, God Almighty and God Most High.
