Matthew 18:4

Whosoever therefore shall humble himself. — This, then, was the answer to the question “Who shall be the greatest.” The secret of true greatness lay in that unconsciousness of being great, which takes the lowest position as that which of right belongs to it. For a man to “humble himself” with the purpose of attaining greatness would frustrate itself, and reduce humility to an hypocrisy. The “pride that apes humility,” the false lowliness of Colossians 2:18, is even more hateful and contemptible than open self-assertion.

As this little child. — That which was to be the result of a deliberate act in the disciples was found in the child’s nature as it was. They were to make themselves lowly as he was lowly. The transition from the plural to the singular gives an almost dramatic vividness to the form of our Lord’s teaching. We seem to see the child shrinking timidly, with blushing face and downcast eyes, from the notice thus drawn to him.
