Jesus says this childlike nature is necessary to enter the kingdom of heaven.

But Jesus said, Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven.

Remember, earth is not heaven!

That's the only thing they have, now all that you would possess in the heavens, this author says,you already possess.

We may want a life of no fears in this world but that only happens in heaven.
