For the law was given by Moses, but grace and truth came by Jesus Christ.
Ver. 17. For the law, &c.] Lex iubet, gratia iuvat. Petamus ut det, quod ut habeamus iubet, The law command, grace assists. Let us ask that he may give, that we have what he commands, saith Augustine. We have his promise ever going along with his precept. The covenant of grace turns precepts into promises, and the Spirit of grace turns both into prayers.
