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:..
James 1:14.. But every man is tempted, when he is drawn away of his
own lust, and enticed...
James 1:15.. Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death...
Bottom line for Jesus to have sinned, He would have had to have LUST. No lust, no sin. Humans that sin, sin because the temptation originates within them (
own lust). The temptation of Jesus was external, not internal. Jesus was just as much God in the flesh as he was in the Creation..."God cannot be tempted with evil". To teach that Jesus who was the eternal God in flesh could/would sin attempts to do damage to the Godhead.
