Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven.
Childlike faith is not childish faith, nor is it mentally inferior or blind faith. I’ve said it many times before: there is no such thing as blind faith, only blind ignorance. Jesus is not telling his followers that they need to be mentally simple or that they should not question and seek honest answers to difficult theological questions.
He continues in v. 4:
Whoever humbles himself like this child is the greatest in the kingdom of heaven.
The lesson here has nothing do with how we know what we know or why we believe what we believe.
At that time the disciples came to Jesus, saying, “Who is the greatest in the kingdom of heaven?”
His followers are arguing over who’s the best among them. Jesus calls them over and uses a child to teach them that greatness in the Kingdom is measured in humility, not pride. Compare this to our current political and athletic icons. Who is truly great?
