The greatest ... - That is, shall be the most eminent Christian shall have most of the true spirit of religion.

Whosoever therefore shall humble himself - So great is the disparity between the kingdom of Christ and the kingdoms of this world, that there is no way of rising to honors in the former, but by humility of mind, and continual self-abasement.

The same is greatest - Thus our Lord shows them that they were all equal, and that there could be no superiority among them, but what must come from the deepest humility; he intimates also, that wherever this principle should be found, it would save its possessor from seeking worldly honors or earthly profits, and from seeking to be a ruler over his brethren, or a lord in God's heritage.

Whosoever therefore shall humble himself,.... Whoever shall entertain mean thoughts of himself, and prefer others to himself, shall behave in a modest humble manner, not affecting dominion over others, or treating his brethren and Christians in a haughty and supercilious manner, with scorn and contempt; but condescend to those of the lowest state, and place himself in the lowest form, conversing with his friends freely and familiarly, without distinction,

as this little child; or any other of the like age; for there is no reason to suppose, that there was anything peculiar in this child, which was not in another, it being common to children to behave towards one another, as on a level; not to envy one another, or to set up one above another, or be vainly elated with the distinctions of birth and fortune.

The same is greatest in the kingdom of heaven; in the Gospel church state; which was verified in the Apostle Paul, though not one of the twelve: nor are these words limited to them; at least, this passage may be illustrated in his case: he thought himself to be the chief of sinners, and less than the least of all saints, and unworthy to be called an apostle; yet had the largest measures of grace, the greatest gifts and abilities; and was honoured with the greatest usefulness and success in the preaching of the Gospel to the conversion of sinners, and planting of churches; labouring more abundantly than they all.

As this little child

Not, as this little child humbles himself, but, shall make himself humble as this little child is lowly; shall willingly become by spiritual process what the child is by nature.

Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven.

18:4 Whosoever therefore shall humble himself as this little child. This explains the great feature in which they must become as the child. Greatness in the kingdom is not secured by seeking to be greatest. There is a lesson here for Christians, and especially preachers who are ambitious of distinction.

18:1-6 Christ spoke many words of his sufferings, but only one of his glory; yet the disciples fasten upon that, and overlook the others. Many love to hear and speak of privileges and glory, who are willing to pass by the thoughts of work and trouble. Our Lord set a little child before them, solemnly assuring them, that unless they were converted and made like little children, they could not enter his kingdom. Children, when very young, do not desire authority, do not regard outward distinctions, are free from malice, are teachable, and willingly dependent on their parents. It is true that they soon begin to show other dispositions, and other ideas are taught them at an early age; but these are marks of childhood, and render them proper emblems of the lowly minds of true Christians. Surely we need to be daily renewed in the spirit of our minds, that we may become simple and humble, as little children, and willing to be the least of all. Let us daily study this subject, and examine our own spirits.
