Again you are in effect saying that God is not almighty and thus cannot manifest Himself as a man.
But the Bible says that God is Spirit, and He is everlasting.
God is a 3 part being (Father, Son, Holy Spirit), just as man is a 3 part being (Soul, body, spirit).
Jesus was God manifest in the flesh (1Timothy 3:16).
This physical manifestation of God is the Alpha (the firstborn of the dead in this physical world, Colossians 1:18), and he is the Omega (the last sacrifice under the law).
And as I pointed out to you Muslims remain in sin as they're anti Christ rejecting Jesus Christ, the Son of God who died for our sin.
As for the Quran, considering that the original Quran, the Hafsah Codex, was destroyed and replaced with a different Quran by a later rival Muslim leadership, and considering the contradictory recitations of it before the Quran was eventually written, and considering the lack of the typical historical evidence that is normally expected for renowned leaders like Mohammed,

it's clear Islam has no leg to stand on.
These inconvenient facts are all available on the web if you want to look further.

Both the Old Testament and the New Testament show that sin leads to death.
But for Christians there is no sin that can be charged against us (Romans 8:33, 1John 3:9, John 8:36), thanks to Christ's sacrifice.
This is the only way one can escape the death penalty for sin.
BTW, I note your silence over the proof I showed from both the Old Testament and the New Testament that Jesus Christ is God.
Anyway folks, I'll be back again tomorrow as it's late night here.
