Read Matthew 18:15-20
If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over. – Matthew 18:15 (NIV)
Sooner or later, we will all sin against others, even others in the church. When someone in the church sins against us, our natural tendency is to push them away, to avoid them, to abandon that relationship. God’s way is for us to intentionally attempt to restore relationship, with gentleness and respect, with the least fuss possible, but with persistence, not giving up on them, just as God does not give up on us.
