Luke 6:32-35

If you love only the people who love you, what praise should you get? Even sinners love the people who love them. If you do good only to those who do good to you, what praise should you get? Even sinners do that! If you lend things to people, always hoping to get something back, what praise should you get? Even sinners lend to other sinners so that they can get back the same amount! But love your enemies, do good to them, and lend to them without hoping to get anything back. Then you will have a great reward, and you will be children of the Most High God, because he is kind even to people who are ungrateful and full of sin.
