But after that faith is come
That is, since Christ the object of faith is come in the flesh, and has fulfilled the law, and redeemed them that were under it from its bondage, curse, and condemnation:
we are no longer under a schoolmaster;
under the law as such; as no longer under it as a military guard, nor in it as a prison, so neither under it as a schoolmaster; not needing its instructions, or its discipline; since Christ is come as a prophet to teach and instruct, as a priest to atone for sin, and make intercession for transgressors, and as a King to rule and govern; in whose hands, and not in the hands of Moses, the law now is, as a rule of walk and conversation.
