Verse 6:1 says, "If anyone is caught in any transgression, you who are spiritual should restore him in a spirit of gentleness.
If you know a fellow Christian who is walking in sin, you should show them love and help them restore their relationship with the Lord. This doesn't mean pointing fingers, condemnation, lectures or the like. This means in GENTLENESS, pray with them, pray for them in your quiet time, remind them of who they are in Jesus, and do what you can, in love, to bring them back to a healthy walk of repentance with the Lord. This text says, "you who are spiritual". This isn't referring to a group of pastors or elders or a 'class of Christians' but more referring to a more mature believer. It would be hard for a believer who is less mature than the one caught in sin to help the struggling one back to a united walk with the Lord. This text encourages a more mature believer to lead the less mature believer back in relationship with the Lord.
Verse 8 says, "For the one who sows to his own flesh, will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit will reap eternal life."
The next verse says, "And let us not grow weary in doing good, for in due season we will reap, if we do not give up."
What are you going to spend your time sowing?
For if anyone things he is something, when he is nothing, he deceives himself.
Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life.
