Matthew 18:1-4 NKJV
At that time the disciples came to Jesus, saying, “Who then is greatest in the kingdom of heaven?”
Then Jesus called a little child to Him, set him in the midst of them, and said, “Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven. Therefore whoever humbles himself as this little child is the greatest in the kingdom of heaven.
