Matthew 12:33

Either make the tree good and his fruit good, or else make the tree corrupt.

Trees of righteousness

There are two kinds of religion in the world: one teaches that men are not so holy as they should be, but that by a little attention they may be improved; the other that men are only evil, and must be made new creatures. The one mends, the other makes. Christ says, Make the tree good.

I. Although the tree has been made good by engrafting, and has consequently begun to bear good fruit, the young trees that spring from the seed of that good fruit, when it is sown again, take after the original bitter root of the parent tree, and not after the sweetness subsequently imparted to it. The child of a Christian man is not by birth a Christian.

II. As the first lesson is one of warning to those who presume upon their privileges, the second is one of encouragement to those who have had in youth no privileges to presume upon. Although a young tree has sprung from the seed of an evil tree, it may be made good by engrafting as effectually as if its parent had been the best in the garden. The unprivileged need not despond.

III. Although an evil tree ought to be made good by engrafting while it is young, it may be made good by engrafting after it has grown old. Some are converted in youth; some have mark and date of conversion more distinct than others.

IV. A tree that has been made good does not again become vii; but latent evil in its roots may, if it be not watched, spring up and bear bad fruit, and mingle with the good, and to a great extent outgrow and choke the good.

V. Although the natural head of the tree, either in youth or age, is cut off, and the new, good branch brought near to touch it, unless the new branch take to the old tree, and the old tree at its wound take to the new branch, so that they become one, no change will be affected in the old tree. The wounds of conviction prepare the way for Christ; but if the wounded do not in the end close with Christ, his wounds will not make him safe or holy. (W. Arnot.)

The grafting mark

In fruit-trees fully grown you may sometimes observe a ring round the stem, midway between the ground and the branches, resembling somewhat the mark of a healed wound on a living man. This indicates the place where the natural stem was cut off and a new branch inserted. You perceive at a glance that this tree has been engrafted, and that it was well grown ere it was made good. In the same garden another tree may grow which exhibits no such mark; yet the owner does not value it less on that account. These two trees are equally good and equally prolific. They differ not in their present character, but in the period of life at which they were severally renewed. This latter tree must have been engrafted when it was very young: the cut was made close to the ground when the stem was very slender; and thus the mark has been obliterated by the subsequent growth of the tree. The cicatrice is concealed under the grass, or perhaps under the ground. The renewing has certainly taken place, but when or where no man can tell. The date of its new birth is no longer legible. Such similarities and such differences obtain also among converted men. Some who were born when they were old bear the mark of their regeneration all their days. When the old nature was matured and developed before the change, the memory of the fact is more distinctly retained, and the contrast more vividly displayed. It was thus in the experience of the Apostle Paul. The spiritual man did not in his case obtain the sway while the natural was yet young and tender and easily moulded. Paul was a man, every inch of him, before he was a Christian. “I verily thought with myself that I ought to do many things contrary to the name of Jesus of Nazareth.” (W. Arnot.)

Two kinds of fruit

One clear example of this tendency I knew well in my youth. I think it remains to this day, and I could point to the spot. A grove given over, by the time I knew it, for the purpose of affording shady pleasure-walks, had originally been a fruit-garden. Some of the old fruit-trees had been left standing as ornaments, when the owner no longer looked for a profitable return. These trees were left growing for the sake of their beauty merely, not for the sake of their fruit. They were allowed, accordingly, to run wild, that their appearance might be more picturesque. An aged pear-tree stood there, with a tall, bare, straight stem and round bushy head like an Eastern palm. But while not a single branch grew on the naked trunk, from where it emerged out of the moss to where its head began to spread at three times the height of a man, a number of lively vigorous shoots sprang from its roots, or rather from its stem where it touched the ground. Thus the long bare stem had a bushy head of branches on either extremity. These lower branches had been permitted to grow freely till they reached maturity on their own account, and bore fruit of their own kind. I have seen fruit growing on these suckers, and fruit hanging at the same time high over them on the tree’s towering head, with a large portion of the bare stem between. I have compared them, and found that which grew from the old root hard and bitter, while that which grew on the head that had been made new, although somewhat deteriorated, retained still the sweet flavour of its best days. Here were two kinds of fruit growing at the same time on one tree-evil fruit growing on the original root, and good fruit growing on that which had been made new. If the tree had been rightly cultivated for the sake of its fruit, those suckers would have been without pity torn off in the bud as soon as they showed themselves, and never have been permitted to open their blossoms or bring forth their fruit. You do not ordinarily see these out-growths from the old stock growing to the size of bearing, on fruit-trees. This, however, is not because they do not manifest a tendency to throw out these shoots, but because the shoots are, in ordinary cases, wrenched off by the husbandman as soon as they appear. (W. Arnot.)

Grafting an old tree

You may see this glory of grace reflected from the field of nature. Perhaps you have looked over the hedge and seen, in a garden by the wayside, a sight that attracted your eye and excited your curiosity. A tree, old, thick, and rusty, has been cut off, not by the ground, but about the height of a man, and the bare stump left standing. On a closer inspection you see one or more small fresh twigs fastened to the bark on the top of the desolate trunk. They are budding and putting out green leaves. It is a tree that had grown old, either barren or bearing bad fruit. Its owner would not longer permit it to occupy uselessly the precious ground. But it is not necessary that he should cut it down and cast it away, in order to make room for another tree. Even this tree, grown old in evil, may be made good. It is not cut down, but cut off, and a new nature engrafted on its stem. Even in old age it will yet be fresh, and flourishing, and fruitful. The owner of the garden counts that he will sooner get a large return by engrafting the old tree than by rooting it out and planting another. The tree was full grown and in vigorous health. The owner will utilize all these powers by sending the sap through a new and better head. It is thus that our Father, the husbandman, takes full-grown vigorous natures, charged with gifts of understanding, and eloquence, and zeal, that have been hitherto occupied with evil, and makes them new creatures by His power. Forthwith they are fit for able-bodied service in the work of the Lord. (W. Arnot.)

The danger of delayed grafting

Let the warning be distinctly, fully given on the other side. If the tree is permitted to grow up and grow old in evil, there is danger lest, by storm or fire, it should be destroyed, and so never be made good. But even although it were insured against all accidents, there is no reason why another, and yet another year an evil tree should cumber the ground, merely to put off the time of its change. (W. Arnot.)
