Mark 10:14-15

14But when Jesus saw this, he was angry. He said to them, ‘Do not stop the children. Let them come to me. People must become like these children so that God can rule their lives. That is what the kingdom of God is like.

15I tell you this: A person must become like a little child for God to rule in his life. If he does not become like a child, he will not come into the kingdom of God.’
