'Credit' in the Bible

If you love those who love you, what credit is that to you? Even sinners love those who love them.

If you do what is good to those who are good to you, what credit is that to you? Even sinners do that.

And if you lend to those from whom you expect to receive, what credit is that to you? Even sinners lend to sinners to be repaid in full.

And, falling down on his face at the feet of Jesus, he gave the credit to him; and he was a man of Samaria.
