The causes of backsliding are many. We have pretended to be living a more devoted life than was actually the case; we neglected to watch unto prayer; we allowed secret sin to eat out the heart of our piety…or we yielded to temptation…or we yielded to the fear of man, and drifted with the multitude to do evil; or we became prosperous, and trusted only in our wealth; or poor, and succumbed to covetousness and the bitterness of despair.
