Second: Just what, therefore, is this work of sanctification? When we are regenerated we have given to us an entirely new nature. The old nature and the new are absolutely different; and the old and the new war one against the other. The Bible is full of the accounts of those who have met this inward conflict. Some of the most eminent people in the world whose names have been mentioned in the Bible and out of it have told the story of their backsliding, their falling, their repentance, and their lamentation because of their weakness. You have all read the seventh chapter of Romans. Whether this is the story of Paul's experience or not, it is the story of yours. Galatians the fifth chapter sixteenth and seventeenth verses gives us the same thought. "This I say then, Walk in the Spirit, and ye shall not fulfill the lust of the flesh. For the flesh lusteth against the spirit, and the Spirit against the flesh: and these are contrary, the one to the other: so that ye cannot do the things that ye would." What is it, therefore? It is just the working day by day of the spirit of Christ in us. It is the growth of that spiritual nature which after a while controls our whole being. It is the bringing into subjection of the old nature until it has no more dominion over us. After Paul's struggle in the seventh chapter of Romans he comes triumphantly to the second verse of the eighth chapter of Romans and exclaims, "For the law of the spirit of life in Christ Jesus hath made me free from the law of sin and death." III It God is the author, then certain things need to be emphasized. First: We need only to be yielding day by day to his efforts and presence and power to become more and more sanctified. His life flows along the path of least resistance; if there is difficulty with us in the matter of temper, sharpness of tongue, an impure mind or an unforgiving spirit, give him liberty and the work is complete. Second: We must learn that the least thing may hinder his work in us. It became necessary for me recently to purchase a hayrake. I was told of two different kinds, one the old-fashioned kind where the prongs of the rake must be lifted by hand, the other an automatic arrangement where by simply touching the foot to a spring the movement of the wheels would lift the rake at the proper time so that raking hay was a delight. The first day the rake was in the field it was almost impossible to use it. It was too heavy to lift by hand and the foot attachment would not work. We sent for the man who had sold us the implement. There was just one little part of the attachment missing. Missing that, hard effort was required and poor work was accomplished. It may be that some little thing stands in the way of your blessing, or the lack of some little thing hinders your usefulness.
