"Finally, brothers, rejoice. Aim for restoration, comfort one another, live in peace; and the God of love and peace will be with you."
2 Corinthians 13:11
Here in one verse is a great encouragement on how to treat eachother, and the blessing that flows to us when we do. Treat eachother with comfort, working for restoration when there's a disagreement or a failing and live in peace and God will be with us.
