'Credit' in the Bible

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

If you do good to those who do good to you, what credit is that to you? For even sinners do the same.

If you lend to those from whom you expect to receive, what credit is that to you? Even sinners lend to sinners in order to receive back the same amount.

For if I do wish to boast I will not be foolish, for I will be speaking the truth; but I refrain from this, so that no one will credit me with more than he sees in me or hears from me.

For what credit is there if, when you sin and are harshly treated, you endure it with patience? But if when you do what is right and suffer for it you patiently endure it, this finds favor with God.
