2 For an answer Jesus called over a child, whom he stood in the middle of the room, 3 and said, "I'm telling you, once and for all, that unless you return to square one and start over like children, you're not even going to get a look at the kingdom, let alone get in. 4 Whoever becomes simple and elemental again, like this child, will rank high in God's kingdom. 5 What's more, when you receive the childlike on my account, it's the same as receiving me.
6 "But if you give them a hard time, bullying or taking advantage of their simple trust, you'll soon wish you hadn't. You'd be better off dropped in the middle of the lake with a millstone around your neck.

Commentary on Matthew 18:1-6
(Read Matthew 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.
