"Superficiality is the curse of our age," declares Richard Foster in this 1978 bestseller, and this theologian's spiritual wake-up call feels even more pertinent today than when it was written. Suggesting that the world urgently needs deeper people rather than merely more talented or intelligent ones, Foster re-introduces the solitary Christian practices of prayer, meditation, and fasting, while stressing the importance of such outward practices as service to others and communal worship. Along with excellent quotations from literature and scripture, Foster includes study questions and suggestions for further reading.
