Matthew 18:2-6 WEB

2 Jesus called a little child to himself, and set him in the midst of them, 3 and said, "Most certainly I tell you, unless you turn, and become as little children, you will in no way enter into the Kingdom of Heaven. 4 Whoever therefore humbles himself as this little child, the same is the greatest in the Kingdom of Heaven. 5 Whoever receives one such little child in my name receives me, 6 but whoever causes one of these little ones who believe in me to stumble, it would be better for him that a huge millstone should be hung around his neck, and that he should be sunk in the depths of the sea.
