'Reward' in the Bible

Rejoice on that day and leap for joy, for your reward in heaven is great [absolutely inexhaustible]; for their fathers used to treat the prophets in the same way.

But love [that is, unselfishly seek the best or higher good for] your enemies, and do good, and lend, expecting nothing in return; for your reward will be great (rich, abundant), and you will be sons of the Most High; because He Himself is kind and gracious and good to the ungrateful and the wicked.

We are suffering justly, because we are getting what we deserve for what we have done; but this Man has done nothing wrong.”
