Matthew 18:1-4

In that hour came the disciples unto Jesus, saying, Who then is greatest in the kingdom of heaven?

And he called to him a little child, and set him in the midst of them,

and said, Verily I say unto you, Except ye turn, and become as little children, ye shall in no wise enter into the kingdom of heaven.

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