Matthew 18:2-6
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.
18:6 “But if anyone causes one of these little ones who believe in me to sin, it would be better for him to have a huge millstone hung around his neck and to be drowned in the open sea.
