“But when the righteous turns away from his righteousness, and commits iniquity, and does according to all the abominations which the wicked man does. Shall he live? None of his righteous deeds which he has done will be remembered. In his trespass that he has trespassed and in his sin that he has sinned, in them will he die.”
God has no pleasure in the death of anyone. But if a righteous man turns away from his righteous living and takes up the way of wickedness, following in the abomination of flagrant disobedience of God's laws, as illustrated in Ezekiel 18:10-12, his past righteousness will not save him. Thus once for all is done away the theory that a man will be measured in scales, the good against the bad. His righteous deeds will not be remembered. There will be nothing to put in the scales. He will be condemned for his current life. Present submission to God's covenant and obedience to His requirements alone can make a man right with God. There is no room for presumption.
Note the differing words used for sin. Here ‘iniquity' is ‘wl speaking of behaving unjustly, doing wrong. ‘Trespass' is m‘l signifying acting counter to one's duty to God. ‘Sin' is chata' meaning to miss the way or the goal, or the mark aimed at. To fall short. (See Judges 20:16 where it means to aim and not miss).
