Matthew 18:1-5

In that hour the disciples came to Jesus saying, Who then is greatest in the kingdom of the heavens? And Jesus having called a little child to him, set it in their midst, and said, Verily I say to you, Unless ye are converted and become as little children, ye will not at all enter into the kingdom of the heavens. Whoever therefore shall humble himself as this little child, he is the greatest in the kingdom of the heavens; and whosoever shall receive one such little child in my name, receives me.
