Luke 18:16

They knew indeed the mystery, that to both nations the call was to be made, (for they entreated for the Canaanitish woman,) but perhaps they were still ignorant of the order. It follows, But Jesus called them unto him, and said, Suffer little children, &c. One age is not preferred to another, else it were hurtful to grow up. But why does He say that children are fitter for the kingdom of heaven? It is because they are ignorant of guile, are incapable of theft, dare not return a blow, are unconscious of lust, have no desire for wealth, honours, or ambition. But to be ignorant of these things is not virtue, we must also despise them. For virtue consists not in our inability to sin, but in our unwillingness. Childhood then is not meant here, but that goodness which rivals the simplicity of childhood.

Hence our Lord pointedly says, of such, not "of these," to show that to character, not to age, is the kingdom given, and to such as have a childlike innocence and simplicity is the promise of the reward.

(Serm. 115.) To whom are they brought to be touched, but to the Saviour? And as being the Saviour they are presented to Him to be saved, who came to save that which was lost. But with regard to these innocents, when were they lost? The Apostle says, By one man sin entered into the world. (Rom. 5:12.) Let then the little children come as the sick to a physician, the lost to their Redeemer.

After what He had said, our Lord teaches us a lesson of humility by His own example; He does not turn away the little children who are brought to Him, but graciously receives them. The wise men of the Gentiles therefore who seek for wisdom in a mystery, which is the kingdom of God, and will not receive this without the evidence of logical proof, are rightly shut out from this kingdom.
