"For this," the Apostle proceeds, "is the will of God, even your sanctification." It is assumed here that the will of God is the law, and ought to be the inspiration, of the Christian. God has taken him out of the world that he may be His, and live in Him and for Him. He is not his own any longer; even his will is not his own; it is to be caught up and made one with the will of God; and that is sanctification. No human will works apart from God to this end of holiness. The other influences which reach it, and bend it into accord with them, are from beneath, not from above; as long as it does not recognise the will of God as its rule and support, it is a carnal, worldly, sinful will. But the will of God, to which it is called to submit, is the saving of the human will from this degradation. For the will of God is not only a law to which we are required to conform, it is the one great and effective moral power in the universe, and it summons us to enter into alliance and co-operation with itself. It is not a dead thing; it is God Himself working in us in furtherance of His good pleasure. To tell us what the will of God is, is not to tell us what is against us, but what is on our side; not the force which we have to encounter, but that on which we can depend. If we set out on an un-Christian life, on a career of falsehood, sensuality, worldliness, God is against us; if we go to perdition, we go breaking violently through the safeguards with which He has surrounded us, overpowering the forces by which He seeks to keep us in check; but if we set ourselves to the work of sanctification, He is on our side. He works in us and with us, because our sanctification is His will. Paul does not mention it here to dishearten the Thessalonians, but to stimulate them. Sanctification is the one task which we can face confident that we are not left to our own resources. God is not the taskmaster we have to satisfy out of our own poor efforts, but the holy and loving Father who inspires and sustains us from first to last. To fall in with His will is to enlist all the spiritual forces of the world in our aid; it is to pull with, instead of against, the spiritual tide.
