James 5:19-20 (NKJV)
19 Brethren, if anyone among you wanders from the truth, and someone turns him
back, 20 let him know that he who turns a sinner from the error of his way will
save a soul from death and cover a multitude of sins.

In these verses we find James, the half brother of Jesus telling Christians
that if anyone turns to sin, someone should attempt to turn them back. And by
turning back the sinner they could possibly save them from death and even save
them from a multitude of other sins.

There is no one who is exempt from wandering away from the truth. Years of
experience or work in the church provides no exclusion from temptation. Based
on everything the bible tells us about the devil just as soon as we deceive
ourselves into thinking we are safe and secure he seeks an opportunity to
destroy us. 1 Corinthians 10:12 says, "Therefore, let him who thinks he stands
take heed lest he fall". So if any of us can fall from grace, then we need to
ensure when we see a Christian brother or sister struggling with sin that we do
what we can to help. So often people want to turn their backs immediately, but
the bible tells us that we should first go and confront their sin and try to
lead them out of the sin. We should never leave them wandering alone on a path
to destruction. Therefore pray for your brothers and sisters in Christ that
they may withstand the temptations of sin. For those who have fallen pray that
Christ would turn them from their sin and give them grace and mercy. Pray that
you may help in their restoration. Ask God what you might do to help another
who has fallen.
