Forgive with no strings attached

Luke 6:27-28, 35

But I tell you who hear: love your enemies, do good to those who hate you, bless those who curse you, and pray for those who mistreat you. But love your enemies, and do good, and lend, expecting nothing back; and your reward will be great, and you will be children of the Most High; for he is kind toward the unthankful and evil.
