James 5:20 (KJV) 20 Let him know, that he which converteth the sinner from the error of his way shall save a soul from death, and shall hide a multitude of sins.
To bring back a believer who wanders from the faith is to save a soul from death. There is a possibility for Christians to err in their ways, to wander from the truth, to come to a point where their souls are in the state of death.
It’s of paramount importance that we don’t leave them without any help and any hope of restoration. They can be restored; they can be saved; their multitude of sins can again be forgiven.
We don’t give up that easily on those who turn away from God. We run after them with all our love. There are those who are obstinate for just a short time; they repent when they’re confronted about their errors. Some may take more time and effort. But we give it our best. Souls are incalculably precious to God; we won’t allow the devil to have them in his grip just like that. Each one is worth fighting for, and fight for our brothers and sisters, we will.
