'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.

For if I want to boast, I will not be a fool, because I will be telling the truth. But I will spare you, so that no one can credit me with something beyond what he sees in me or hears from me,

For what credit is there if you sin and are punished, and you endure it? But when you do what is good and suffer, if you endure it, this brings favor with God.
