None of the sins that person has committed will be remembered against them.

Jeremiah 33:1-18

The word of the Lord came to me: “Son of man, speak to your people and say to them: ‘When I bring the sword against a land, and the people of the land choose one of their men and make him their watchman, and he sees the sword coming against the land and blows the trumpet to warn the people, then if anyone hears the trumpet but does not heed the warning and the sword comes and takes their life, their blood will be on their own head. Since they heard the sound of the trumpet but did not heed the warning, their blood will be on their own head. If they had heeded the warning, they would have saved themselves. But if the watchman sees the sword coming and does not blow the trumpet to warn the people and the sword comes and takes someone’s life, that person’s life will be taken because of their sin, but I will hold the watchman accountable for their blood.

Son of man, I have made you a watchman for the people of Israel; so hear the word I speak and give them warning from me. 

Say to them, ‘As surely as I live, declares the Sovereign Lord, I take no pleasure in the death of the wicked, but rather that they turn from their ways and live. Turn! Turn from your evil ways! Why will you die, people of Israel?

If I tell a righteous person that they will surely live, but then they trust in their righteousness and do evil, none of the righteous things that person has done will be remembered; they will die for the evil they have done. 

None of the sins that person has committed will be remembered against them. They have done what is just and right; they will surely live.

Why?

To be a watchman has the duty to warn other people, everyone has to take their responsibility. To be Christian would mean to be God's watchman and tell others the warning of the Lord. 

Righteousness man doing the right things is good, but his former good deed can't protect him if he turns to evil. The judge's time is in hands of the Lord. Evildoers who committed their sins will be remembered no more.

No one is righteousness man in the world, so do our best to do the right things and always commit our sins before the Lord.

How?

Be humble, be strong, and be faithful before the Lord, God's blessing will be my way and my life.
