God said,
The True Christ shall cry unto him My Father and My God.
But the Antichrist will make himself God.
Psalm 89:26-27 KJV
He shall cry unto me, Thou art my father, my God, and the rock of my salvation. Also I will make him my firstborn, higher than the kings of the earth.
John 20:17 KJV
True Christ saith unto Mariam, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.
2 Thessalonians 2:4 KJV
But Antichrist opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
The Roman Jesus is sitting in God's temple ( which is the Heart and body of those that worship God) and showing himself as God.
