Matthew 18: 1 - 5, 10
At that time the disciples came to Jesus, saying, "Who is the greatest in the kingdom of heaven?"
And calling to him a child, he put him in the midst of them,
and said, "Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven.
Whoever humbles himself like this child, he is the greatest in the kingdom of heaven.
"Whoever receives one such child in my name receives me;
"See that you do not despise one of these little ones; for I tell you that in heaven their angels always behold the face of my Father who is in heaven.
