III. Lastly, let me say a word about the triumphant solution.
Law says, 'Make the tree good,' and does not try to do it. Christ said, 'Make the tree good,' and proceeds to do it. And how does He do it?
He does it by coming to us; to every soul of man on the earth, and offering, first, forgiveness for all the past. I do not know that amongst all the bonds by which evil holds a poor soul that struggles to get away from it, there is one more adamantine and unyielding than the consciousness that the past is irrevocable, and that 'what I have written I have written,' and never can blot out. But Jesus Christ deals with that consciousness. It is true that 'whatsoever a man soweth that shall he also reap,' and the Christian doctrine of forgiveness does not contradict that solemn truth, but it assures us that God's heart is not turned away from us, notwithstanding the past, and that we can write the future better, and break altogether the fatal bond that decrees, apart from Him, that 'to-morrow shall be as this day, and much more abundant,' and that past sin shall beget a progeny of future sins. That fruitfulness of sin is at an end, if we take Christ for our Saviour.
He makes the tree good in another fashion still; for the very centre, as it seems to me, of the Gospel of Jesus Christ is that into our spirits He will breathe a new life kindred with His own, a new nature which is free from the law and bonds of past sin, and of present and future death. The tree is made good because He makes those who believe in Him 'new creatures in Christ Jesus.' Now, do not turn away and say that that is mysticism. Be it mysticism or not, it is God's truth. It is the truth of the Christian Revelation, that faith in Jesus Christ puts a new nature into any man, however sinful he may have been, and however deep the marks of the fetters may have been upon his limbs.
Christ makes the tree good in yet another fashion, because He brings to the reinforcement of the new life which He imparts the mightiest motives, and sways by love, which leads to the imitation of the Beloved, which leads to obedience to the Beloved, which leads to shunning as the worst of evils anything that would break the communion with the Beloved, and which is in itself the decentralising of the sinful soul from its old centre, and the making of Christ the Beloved the centre round which it moves, and from which it draws radiance and light and motion. By all these methods, and many more that I cannot dwell upon now, the problem is triumphantly solved by Christianity. The tree is made good, and 'instead of the briar shall come up the myrtle tree.'
