Matthew 5:9, 16, 23-24, 44-45

They are blessed who work for peace, for they will be called God’s children.

In the same way, you should be a light for other people. Live so that they will see the good things you do and will praise your Father in heaven.

“So when you offer your gift to God at the altar, and you remember that your brother or sister has something against you, leave your gift there at the altar. Go and make peace with that person, and then come and offer your gift.

But I say to you, love your enemies. Pray for those who hurt you. If you do this, you will be true children of your Father in heaven. He causes the sun to rise on good people and on evil people, and he sends rain to those who do right and to those who do wrong.
