The Bible says: “The person who has God’s approval will live by faith. But if he turns back, I will not be pleased with him.” (Heb 10:38 NOG)
There is really no such thing as a sudden fall. Oh! The last step is only the last of a series of steps. I believe there are always many steps before a child of God reaches the verge of the precipice.
I believe, further, that even when the edge of the precipice is reached, very few jump over. Most of them slide down, slowly at first & it is so easy, so gentle, so effortless, so natural, so pleasant, that, alas! Alas! They seem to enjoy the sensation.
It is only when the pace begins to accelerate terribly, it is only when control is slipping away, that this pleasant enjoyment gives way to anxiety & alarm.
“The Christian life is very much like climbing a hill of ice. You cannot slide up. You have to cut every step with an ice axe. Only with incessant labor in cutting and chipping can you make any progress. If you want to know how to backslide, leave off going forward. Cease going upward and you will go downward of necessity. You can never stand still.” - Charles Spurgeon.
