Matthew 18: 1-5 (KJV)
At the same time came the disciples unto Jesus, saying, Who is the greatest in the kingdom of heaven? And Jesus called a little child unto him, and set him in the midst of them, And said, verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. Whosoever shall humble himself as this little child, the same is the greatest in the kingdom of heaven. And whoso shall receive one such little child in my name receiveth me.
