Mercy makes us different
Showing kindness or mercy to people who deserve it doesn’t make waves; it’s expected. Even people in the world who hate Jesus can do that.
If you love only those who love you, why should you get credit for that? Even sinners love those who love them! Love your enemies! Do good to them. Lend to them without expecting to be repaid. Then your reward from heaven will be very great, and you will truly be acting as children of the Most High, for he is kind to those who are unthankful and wicked.
