Matthew 18:3,4 - Joseph Benson’s Commentary on the Old and New Testaments

And said, Verily I say unto you What I say is an undoubted and most important truth, a truth which you ought not only firmly to believe but seriously to lay to heart: except ye be converted Turned from these worldly and carnal views and desires; and become like little children “Free from pride, covetousness, and ambition, and resemble them in humility, sincerity, docility, and disengagement of affection from the things of the present life, which excite the ambition of grown men,” ye shall be so far from becoming the greatest in my kingdom, that ye shall not so much as enter into it. Observe well, reader, the first step toward entering into the kingdom of grace is to become as little children: lowly in heart, knowing ourselves utterly ignorant and helpless, and hanging wholly on our Father who is in heaven, for a supply of all our wants. We may further assert, (though it is doubtful whether this text implies so much,) except we be turned from darkness to light, and from the power of Satan to God: except we be entirely, inwardly changed, and renewed in the image of God, we cannot enter into the kingdom of glory. Thus must every man be converted in this life, or he can never enter into life eternal. Whosoever therefore shall humble himself He that has the greatest measure of humility, joined with the sister graces of resignation, patience, meekness, gentleness, and long-suffering, shall be the greatest in Christ's kingdom: whosoever rests satisfied with the place, station, and office which God assigns him, whatever it may be, and meekly receives all the divine instructions, and complies with them, though contrary to his own inclinations, and prefers others in honour to himself, such a person is really great in the kingdom of heaven, or of God.
