Idling in Intellectual Neutral

Came across this quote in a class I’m taking:

Our churches are filled with Christians who are idling in intellectual neutral. As Christians, their minds are going to waste. One result of this is an immature, superficial faith. People who simply ride the roller coaster of emotional experience are cheating themselves out of a deeper and richer Christian faith by neglecting the intellectual side of that faith. (William Lane Craig)

At the same time, I suspect there is another number of Christians who are idling in emotional neutral. Their hearts are beginning to harden. They rarely feel; they always reason. Pangs of sadness for the hurting are absent, only a dim satisfaction with the current status quo.

If only our hearts and minds were in gear!
