Do the good deeds of a lost person help him before God?

No. According to Romans 6:23, the wages of sin is death, and everything a lost person does—good or bad—piles up wages for eternal doom. Salvation is not earned by works; it is the gift of God, eternal life through Jesus Christ.

The teaching explains that Romans 6:23 contrasts wages and gift. Wages are what you work for and what you deserve, while the old Adamic nature we are born with has only one direction: death, eternal death. Therefore, everything a lost person does, whether good or bad, is piling up wages for his eternal doom. Good deeds do not change that. But the flip side is the gift of God: eternal life through Jesus Christ our Lord. A gift is something you do not deserve and cannot earn by even one iota of work; salvation must be a gift.

Romans 6:23

For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.

What happens to the works of a lost person, whether good or bad?

Everything a lost person does, whether good or bad, piles up wages for eternal doom. Because the old Adamic nature is directed only toward death, even good deeds cannot earn salvation. Wages are what one works for, while eternal life is God’s gift through Jesus Christ, not earned by any work.
