Contradiction with James 1:13
This verse states that God cannot be tempted with evil, which contradicts Hebrews 2:18, where it mentions that Jesus suffered being tempted.
James 1:13: Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man: [evil: or, evils]
Contradiction with 1 John 3:5
It claims that in Jesus there is no sin, which may seem contradictory because Hebrews 2:18 suggests Jesus was tempted, implying susceptibility.
1 John 3:5: And ye know that he was manifested to take away our sins; and in him is no sin.
Contradiction with Hebrews 4:15
While it mentions Jesus was tempted in all ways like us but without sin, it subtly contrasts with Hebrews 2:18 by emphasizing His sinlessness despite temptations.
Hebrews 4:15: For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as [we are, yet] without sin.
Contradiction with John 8:29
States that Jesus always does things that please God, contrasting with the implication in Hebrews 2:18 that temptation might mean a struggle to remain sinless.
John 8:29: And he that sent me is with me: the Father hath not left me alone; for I do always those things that please him.
