Matthew 18:2-6

2Jesus invited a little child to stand among them. 3“Truly I tell you,” He said, “unless you change and become like little children, you will never enter the kingdom of heaven. 4Therefore, whoever humbles himself like this little child is the greatest in the kingdom of heaven. 5And whoever welcomes a little child like this in My name welcomes Me.

6But if anyone causes one of these little ones who believe in Me to stumble, it would be better for him to have a large millstone hung around his neck and to be drowned in the depths of the sea.
