Of all approaches to God, prayer is the best and in the final analysis the only means. In the act of prayer, the human mind finds its noblest expression. The mental state of the scientist engaged in research, of the artist creating a work of art, of the thinker wrapped up in philosophy - even of professional theologians propounding their doctrines - cannot be compared to that of the man of prayer brought face to Face with the living God. Each and every kind of mental activity presents less of a strain than prayer. We may be capable of working for ten or twelve hours on end, but a few moments of prayer and we are exhausted.
