John Owen – How to Set Your Affections on Things Above, Chapter 4

“…

let men examine themselves what number of these vain, useless thoughts night and day do rove up and down in their minds. If now it be apprehended too severe, that men’s thoughts of spiritual things should exceed them that are employed about their lawful callings, let them consider what proportion they bear unto those that are vain and useless. Do not many give more time unto them than they do unto holy meditations, without an endeavor to mortify the one or to stir up and enliven the other? are they not more wonted to their seasons than holy thoughts are? And shall we suppose that those with whom it is so are spiritually minded?”
