'Credit' in the Bible

"And if you love those who love you, what kind of credit is [that] to you? For even sinners love those who love them!

And if you do good to those who do good to you, what kind of credit is [that] to you? Even the sinners do the same!

And if you lend [to those] from whom you expect to receive [back], what kind of credit is [that] to you? Even sinners lend to sinners, so that they may get back an equal [amount]!

For if I want to boast, I will not be foolish, because I will be telling the truth, but I am refraining, so that no one can credit to me more than what he sees [in] me or hears anything from me,

not stealing, but demonstrating all good faith, in order that they may do credit to the teaching of God our Savior in everything.

For what credit [is it] if, [when you] sin and are beaten [for it], you endure? But if you endure [when you] do good and suffer [for it], this [finds] favor with God.
