Matthew 5:23-24 (NIV)
23“Therefore, if you are offering your gift at the altar and there remember that your brother has something against you,
24leave your gift there in front of the altar. First go and be reconciled to your brother; then come and offer your gift.
2 Corinthians 13:11 (ESV)
Finally, brothers, rejoice. Aim for restoration, comfort one another, agree with one another, live in peace; and the God of love and peace will be with you.
