Render good for evil

1. You have learned that it was said: “You shall love your neighbor and hate your enemies.”  But I say  to you: Love  your  enemies;  do good to those who hate you and pray for those who persecute and malign you so that you may be children of your Father who is in heaven, who makes the sun rise on the good and on the evil, and the rain fall on the just and the unjust, for if you love only those who love you, what reward will you receive from it? Do not the Publicans  also do that? And if you greet only your brothers, what are you doing that others do not? Do not the Publicans do the same? I say to you that if your justice is not more abundant  than that of the scribes and the Pharisees, you will not enter the kingdom of heaven. (Mt. 5:20, 43-47)

2. If you love only those who love you, what reward will you have, since even sinners also love those who love them? And if you do good only to those who do good to you, what reward will you have, since even sinners do the same thing? And if you lend only to those from whom you can expect the same favor, what reward will you have, since even sinners lend to each another in order to receive the same advantage? But as for you, love your enemies, do good to all and lend without expecting anything, and then your reward will be very great and you will be children of the Most High, who is good to ingrates and even the wicked. Thus, be full of mercy just as your God is full of mercy. (Lk. 6:32-36)
