I've already added this quote to Underlined Bits, but thought it was worth putting here too.
Jesus Christ is refreshing, but flight from him into Christless leisure
makes the soul parched. At first it may feel like freedom and fun to skimp on
prayer and neglect the Word, but then we pay: shallowness, prayerlessness,
vulnerability to sin, preoccupation with trifles, superficial relationships, and
a frightening loss of interest in worship and the things of the Spirit.
John Piper (1997) A Godward Life, in ch.34 "Setting Our Minds on Things Above in Summer"
