But if a wicked person turns away from all his sins that he has committed and keeps all my statutes and does what is just and right, he shall surely live; he shall not die.
Ezekiel 18:21
If the wicked will save himself from God's wrath, he will repent from sin and keep God's Law. Salvation has ALWAYS been by faith in God's mercy, never by obedience to a list of rules, but a refusal to obey is a rejection of God's mercy. You cannot be saved from God's wrath while refusing to repent of sin.
