Yet it is not an easy thing to pray. There is a price to be paid, a price of curbed freedom, of resolute concentration, of agonizing supplication. Prayer is the acid test of devotion. To stay in the presence of God and to wait upon him, bearing your soul to His searching gaze, costs everything. The one who prays must be transformed. Prayer must make him holier, purer, more Christ-like. Prayer is a purifying medium.Colin Peckham, from Sounds from Heaven, The Revival on the Isle of Lewis 1949-1952.
