Ezekiel 18:24

But when a righteous person turns away from his righteousness and does injustice and does the same abominations that the wicked person does, shall he live? None of the righteous deeds that he has done shall be remembered; for the treachery of which he is guilty and the sin he has committed, for them he shall die. (Ezekiel 18:24)

Three points:

1. Some people feel that if they do more good than evil, God will let them into heaven.

They hope the balance tips in favor of good, hoping they have done more good than evil.

2. Righteous can become unrighteous.

Some turn from doing what is right and start doing what is evil. In our passage's context there are some things listed that are evil.

Then suppose this man has a son who robs and kills, who does any of these things that the father never did. He eats sacrifices offered at forbidden shrines and seduces other men's wives. He cheats the poor, he robs, he keeps what a borrower gives him as security. He goes to pagan shrines, worships disgusting idols, and lends money for profit. Will he live? No, he will not. He has done all these disgusting things, and so he will die. He will be to blame for his own death. (Ezekiel 18:10-13)

3. There is a remedy.

But the tax collector, standing far off, would not even lift up his eyes to heaven, but beat his breast, saying, 'God, be merciful to me, a sinner!' (Luke 18:13)
