Three continuing uses
Allowing then that every believer has done with the law, as it means the Jewish ceremonial law, or the entire Mosaic dispensation (for these Christ has taken out of the way) yes, allowing we have done with the moral law, as a means of procuring our justification (for we are justified freely by his grace, through the redemption that is in Jesus). Yet in another sense, we have not done with this law. For it is still of unspeakable use, first, in convincing us of the sin that yet remains both in our hearts and lives, and thereby keeping us close to Christ, that his blood may cleanse us every moment; secondly, in deriving strength from our head into his living members, whereby he impowers them to do what his law commands; and thirdly, in confirming our hope of whatever it commands, and we have not yet attained, of receiving grace upon grace, till we are in actual possession of the fullness of his promises.

4. *Allowing then that every believer has done with the law, as it means the Jewish ceremonial law, or the entire Mosaic dispensation (for these Christ hath taken out of the way) yea, allowing we have done with the moral law, as a means of procuring our justification (for we are justified freely by his grace, thro’ the redemption that is in Jesus). Yet in another sense, we have not done with this law. For it is still of unspeakable use, first, in convincing us of the sin that yet remains both in our hearts and lives, and thereby keeping us close to Christ, that his blood may cleanse us every moment; secondly, in deriving strength from our head into his living members, whereby he impowers them to do what his law commands; and thirdly, in confirming our hope of whatsoever it commands, and we have not yet attained, of receiving grace upon grace, till we are in actual possession of the fulness of his promises.
