A backslider is one who has experientially removed himself from the grace of God. Another, who has fallen through weakness, has the protection of everlasting arms beneath him which upholds him in grace (Deuteronomy 33:27). While both fell in sin, one is filled with his own ways while the other is empty in weakness and frailty, waiting for the filling and renewal of the Spirit through faith. When one is in a condition wherein he needs a statement from God as a promise, he should wait for the revelation of the promise and not wait for the fulfillment of its contents.
We do not have to wait without life. We have an all-sufficient God whose qualities provide all in all situations. He is not just sufficient for situations which complement the display of His life. He is all in even the most difficult trial. He has a ministry of life that is eternally able to reveal itself. When you are removed from Him and placed in self, then all you see will be according to sight. Your perspective on truth is regulated by what fills you.
Similarly, if your glasses are tinted blue, things will not appear the same to you as they appear to others. Is what you receive colored by your glasses? People who have removed themselves from grace do not view faith as the logical way to go because they are not filled with the Spirit. It is better to start off blind and then receive the touch of the Master’s life than to let your life be tinted so that you cannot see with the clarity of God’s mind.
