Those who are themselves blessed in Christ should desire to have their children also blessed in him, and should hereby testify the true honour they have for Christ, by their making use of him, and the true love they have for their children, by their concern about their souls. They brought to him infants, very young, not able to go, sucking children, as some think. None are too little, too young, to bring to Christ, who knows how to show kindness to them that are not capable of doing service to him.
Jesus did not say that God’s kingdom belongs “to these” but “to such as these.” Jesus was not saying that all children, simply because they are children, have received God’s kingdom (Luke 18:17). Jesus was not attributing to children an innate goodness. Rather, he appealed to some quality possessed by little children that is essential for entering God’s kingdom.
Such humility is of course accompanied by repentance and faith, but the emphasis here is on humility. Only the last, who humble themselves, shall enter the kingdom. The first in their self-exaltation see no need to humble themselves and accept God’s grace (13:30; 14:11; 18:14).
