Matthew 18:2-5

18:2 He called a child, had him stand among them, 18:3 and said, “I tell you the truth, unless you turn around and become like little children, you will never enter the kingdom of heaven! 18:4 Whoever then humbles himself like this little child is the greatest in the kingdom of heaven. 18:5 And whoever welcomes a child like this in my name welcomes me.
