Luke 6:34-35

6:34 And if you lend to those from whom you hope to be repaid, what credit is that to you? Even sinners lend to sinners, so that they may be repaid in full. 6:35 But love your enemies, and do good, and lend, expecting nothing back. Then your reward will be great, and you will be sons of the Most High, because he is kind to ungrateful and evil people.
