Dietrich Bonehoeffer once wrote: "The child poses a problem to theology." What he meant, or what I think he meant, is that 'if one enters the Kingdom by becoming like a child, what about systematic theology and the rigorous intellect that is required?' As Bonehoeffer rightly asserts, this is a problem for theology, not a devastating blow. But a problem nevertheless, too often our elegant theological structures exist only ideas. The child knows nothing of the idea's elegance, but instead of trust, experience, and love.
J.I. Packer talks about how theology must lead to doxology. That the knowledge of God should lead to the praise of God; child-like enamored soft-hearted and wild-eyed praise.
