20 The person who sins is the one who will die. The child will not be punished for the parent's sins, and the parent will not be punished for the child's sins. Righteous people will be rewarded for their own righteous behavior, and wicked people will be punished for their own wickedness.

God's Way Is Just

21 But if wicked people turn away from all their sins and begin to obey my decrees and do what is just and right, they will surely live and not die. 22 All their past sins will be forgotten, and they will live because of the righteous things they have done.

Matthew Henry's Commentary on Ezekiel 18:20-22

Commentary on Ezekiel 18:1-20

(Read Ezekiel 18:1-20)

The soul that sinneth it shall die. As to eternity, every man was, is, and will be dealt with, as his conduct shows him to have been under the old covenant of works, or the new covenant of grace. Whatever outward sufferings come upon men through the sins of others, they deserve for their own sins all they suffer; and the Lord overrules every event for the eternal good of believers. All souls are in the hand of the great Creator: he will deal with them in justice or mercy; nor will any perish for the sins of another, who is not in some sense worthy of death for his own. We all have sinned, and our souls must be lost, if God deal with us according to his holy law; but we are invited to come to Christ. If a man who had shown his faith by his works, had a wicked son, whose character and conduct were the reverse of his parent's, could it be expected he should escape the Divine vengeance on account of his father's piety? Surely not. And should a wicked man have a son who walked before God as righteous, this man would not perish for his father's sins. If the son was not free from evils in this life, still he should be partaker of salvation. The question here is not about the meritorious ground of justification, but about the Lord's dealings with the righteous and the wicked.

Commentary on Ezekiel 18:21-29

(Read Ezekiel 18:21-29)

The wicked man would be saved, if he turned from his evil ways. The true penitent is a true believer. None of his former transgressions shall be mentioned unto him, but in the righteousness which he has done, as the fruit of faith and the effect of conversion, he shall surely live. The question is not whether the truly righteous ever become apostates. It is certain that many who for a time were thought to be righteous, do so, while 28 is the beginning and progress of repentance. True believers watch and pray, and continue to the end, and they are saved. In all our disputes with God, he is in the right, and we are in the wrong.
