I know with any man the power of evil in my heart; and while it may come, as it were, in spite of myself, I can determine the question as to whether it shall stay. It is the vilest heresy of our day to preach and believe that circumstances can absolve us from our duty; or that they can prevent us from following the right. The battle is hard, at times very hard, but what battle is not hard that is worth winning? Put religion out of the question, and do we find that the prizes of the world offer us easier terms? It is the greatness of the Christian religion, that it not only tells us what it were good to do, but it offers to us the power to do it. The great teachers of the world have said to their disciples: "Accept our ideas"; Christ says: "Accept Me." "He makes everything centre in His Own Personality." And the men who have helped to make what so far in our human world is grand and glorious, have shown us that Christ's word is a real word, meaning a real thing. One who has the right to testify has told us that, when we do the will of God as if it were our own will, we realize that God is doing our will as His own. There is a great truth in this. We so often fail because ours is a broken obedience. We expect God to do His part, while we keep back part of the price of our own, and what response we have is the sense of being mocked in ourselves. We have to find out that we cannot serve two masters. However we fall short in practice, the intention must be all for God, or it will be none. But let us be genuine co-workers with Him in this great work of personal character-building; and we find that we have a power not ourselves, and infinitely greater than ourselves. Our achievements are not so much a question of gift, as of dynamic. They are not in the machinery, but in the driving power. "How is it"--was a question recently asked concerning one of the most useful men in the Christian ministry--"that with his obvious limitations he has accomplished so much?" And the answer was: "Because he has made it possible for God to use him for all he is worth." Failure is impossible in the man who can say: "I live, and yet not I, but Christ liveth in me." We cannot explain the power; but it is there, and we all may have it by obedience to the conditions through which it can be given. "I have been down deep in the hell of moral failure," writes one, "and by the grace of God I have come out of it. I may not be able to explain His grace to the satisfaction of others; but will others explain me to my own?" Our lives may be the living evidences of this power. The world asks for no more; the world will accept no less. Our day, we are told, has ceased to believe in such miracles. It were truer to say that it has ceased to believe in anything else.
