"he should know that whoever brings back a sinner from the error of his way will save his soul from death and will cover a multitude of sins" James 5:20
Meaning:
When a Christian is instrumental in the conversion of a sinner, the result is forgiveness of sins and a reinstatement of the sinner to the life of grace.
James 5:19,20 - Brethren, if anyone among you wanders from the truth, and someone turns him back, let him know that he who turns a sinner from the error of his way will save his soul from death and cover a multitude of sins. ~ Note: If the backslider does not get corrected, his soul will perish with spiritual death. That is not everlasting life. The word wanders also means to sever or fall away from the truth, to be led astray into error and sin. The word from also means of departing, of fleeing, of any kind of separation of one thing from another by which the union or fellowship of the two is destroyed. Clearly, this is about brethren who are no longer saved. The word turns also means to cause to return, to bring back to the love and obedience of God. That's part of what I'm trying to do with this web page. The word save also means to preserve one who is in danger of destruction. The word death is the same one in 1:15 above and it also means with the implied idea of future misery in hell, the misery of the soul arising from sin, which begins on earth but lasts and increases after the death of the body in hell.
