He shows the conditions of entrance into and eminence in His kingdom by a living example. There were always children at hand round Him, when He wanted them. Their quick instinct for pure and loving souls drew them to Him; and this little one was not afraid to be taken by the hand, and to be afterwards caught up in His arms, and pressed to His heart. One does not wonder that the legend that he was Ignatius the martyr should have been current; for surely the remembrance of that tender clasping arm and gentle breast would not fade nor be fruitless. The disciples had made very sure that they were to be in the kingdom, and that the only question concerning them was how high up in it they were each to be. Christ's answer is like a dash of cold water to that confidence. It is, in effect,' Greatest in the kingdom! Make sure that you go in at all, first; which you will never do, so long as you keep your present ambitious minds.'
Matt. 18:3 lays down the condition of entrance into the kingdom, from which necessarily follows the condition of supremacy in it. What a child is naturally, and without effort or merit, by reason of age and position, we must become, if we are to pass the narrow portal which admits into the large room. That becoming' is impossible without a revolution in us. Be converted' is corrected, in the Revised Version, into turn,' and rightly; for there is in the word a distinct reference to the temper of the disciples as displayed by their question. As long as they cherished it they could not even get inside, to say nothing of winning promotion to dignities in the kingdom. Their very question condemned them as incapable of entrance. So there must be a radical change, not unaccompanied, of course, with repentance, but mainly consisting in the substitution of the child's temper for theirs. What is the temper thus enjoined? We are to see here neither the entirely modern and shallow sentimental way of looking at childhood, in which popular writers indulge, nor the doctrine of its innocence. It is not Christ's teaching, either that children are innocent, or that men enter the kingdom by making themselves so. But the child is, by its very position, lowly and modest, and makes no claims, and lives by instinctive confidence, and does not care about honours, and has these qualities which in us are virtues, and is not puffed up by possessing them. That is the ideal which is realised more generally in the child than analogous ideals are in mature manhood. Such simplicity, modesty, humility, must be ours. We must be made small ere we can enter that door. And as is the requirement for entrance, so is it for eminence. The child does not humble himself, but is humble by nature; but we must humble ourselves if we would be great.
Christ implies that there are degrees in the kingdom. It has a nobility, but of such a kind that there may be many greatest; for the principle of rank there is lowliness. We rise by sinking. The deeper our consciousness of our own unworthiness and weakness, the more capable are we of receiving the divine gifts, and therefore the more fully shall we receive them. Rivers run in the hollows; the mountain-tops are dry. God works with broken reeds, and the princes in His realm are beggars taken from the dunghill. A lowliness which made itself lowly for the sake of eminence would miss its aim, for it would not be lowliness. The desire to be foremost must be cast out, in order that it may be fulfilled.
