Love your enemies, do good to those who hate you, bless those who curse you, pray for those who mistreat you. If someone slaps you on one cheek, turn to them the other also. If someone takes your coat, do not withhold your shirt from them. Give to everyone who asks you, and if anyone takes what belongs to you, do not demand it back. Do to others as you would have them do to you. Luke 6:27-31
“What is the reason for this Christian conduct? The reason is that it makes us like God, for that is the way he acts. God’s sends his rain on the just and the unjust. He is kind to the person who brings him joy and equally kind to the person who grieves his heart. God’s love embraces saint and sinner alike. It is that love we must copy; if we, too, seek even our enemy’s highest good we will in truth be the children of God.”
