YAHWEH did not become flesh to die to commute the death sentence which is irrevocable for any sin while the believer will continue to sin.
YAHWEH says that He came to call the sinners unto repentance. Repentance implies 'the choice to no longer sin for remission of sins'.
Sin is disagreeing with God as the Sepent disagreed with God and enticed Eve to eat of the forbidden tree and acted in disagreement with God.
Whoever disagrees with God in any iota of His voice in Moses and the Prophets (Luke 16:27-31) is a sinner.
To wit, Jesus says that He is YAHWEH in John 8:24. Anyone who disagrees with John 8:24 cannot be saved by Yehoshua (Jesus) Messiah YHWH.
When I say to the righteous, that he shall surely live; if he trust to his righteousness, and commit iniquity, none of his righteous deeds shall be remembered; but in his iniquity that he hath committed, therein shall he die.
For whosoever shall keep the whole law, and yet stumble in one point, he is become guilty of all.
