Matthew 18:2-6 CSB
He called a small child and had him stand among them. “Truly I tell you,” he said, “unless you turn and become like little children, you will never enter the kingdom of heaven. Therefore, whoever humbles himself like this child — this one is the greatest in the kingdom of heaven. And whoever welcomes one child like this in my name welcomes me.
“But whoever causes one of these little ones who believe in me to fall away — it would be better for him if a heavy millstone were hung around his neck and he were drowned in the depths of the sea.
