'Right' in the Bible

This is a positive proof of the righteous judgment of God [a sign of His fair verdict], so that you will be considered worthy of His kingdom, for which indeed you are suffering.

not because we do not have a right to such support, but [we provided our own financial support] to offer ourselves as a model for you, so that you would follow our example.

And as for [the rest of] you, believers, do not grow tired or lose heart in doing good [but continue doing what is right without weakening].
