18. But if ye be led by the Spirit. In the way of the Lord believers are apt to stumble. But let them not be discouraged, because they are unable to satisfy the demands of the law. Let them listen to the consolatory declaration of the apostle, which is also found in other parts of his writings, (Romans 6:14,) ye are not under the law. Hence it follows, that the performance of their duties is not rejected on account of their present defects, but is accepted in the sight of God, as if it had been in every respect perfect and complete. Paul is still pursuing the controversy about freedom. The Spirit is elsewhere (Romans 8:15) denominated by him, “the Spirit of adoption;” and when the Spirit makes men free, he emancipates them from the yoke of the law. As if he had said, “Is it your desire instantly to terminate the controversies in which you are now engaged? Walk according to the Spirit. You will then be free from the dominion of the law, which will act only in the capacity of a kind adviser, and will no longer lay a restraint upon your consciences.” Besides, when the condemnation of the law is removed, freedom from ceremonies follows as a necessary consequence; for ceremonies mark the condition of a slave.
