Philip Yancey ins his book “DISAPPOINTMENT WITH GOD writes:
I found that for many people there is a large gap between what they expect from their Christian faith and what they actually experience. From a steady diet of books, sermons, and personal testimonies, all promising triumph and success, they learn to expect dramatic evidence of God working in their lives. If they do not see such evidence, they feel disappointment, betrayal and often guilt.” Philip Yancey
C.S. Lewis nails it when he writes in Mere Christianity:
“Either we give up trying to be good, or else we become very unhappy indeed. For, make no mistake: If you are really going to try to meet all the demands made on the natural self, it will not have enough left over to live on. The more you obey your conscience, the more your conscience will demand of you. And your natural self, which is thus being starved and hampered and worried at every turn, will get angrier. In the end, you will either give up trying to be good, or else become one of those people who, as they say, “live for others” but always in a discontented, grumbling way – always making a martyr of yourself. And once you have become that you will be a far greater pest to anyone who has to live with you than you would have been if you had remained frankly selfish.”
Ralph Waldo Emerson said:
“The God of the cannibals will be a cannibal, of the crusaders a crusader, and of the merchant, a merchant.”
