'Perform' in the Bible

I have a duty to perform and a debt to pay both to Greeks and to barbarians [the cultured and the uncultured], both to the wise and to the foolish.

For I know that nothing good lives in me, that is, in my flesh [my human nature, my worldliness—my sinful capacity]. For the willingness [to do good] is present in me, but the doing of good is not.
