From John Piper's book Think:
Any knowledge that does not stand in the service of love is not real knowing. It is prostituted knowing. It's as though God put surgical tools in our hands and taught us how to save the sick, but we turned them into a clever juggling act while the patients died. Knowing and thinking exist for the sake of love -- for the sake of building people up in faith. Thinking that produces pride instead of love is not true thinking. We only imagine that we are thinking. God does not see it as thinking. It's not surgery; it's juggling.
