One is, that this work, this work of power which they have been made partakers of, has not been thorough enough upon all the powers of their souls. Their understandings, their judgments and consciences have been dealt with, but the power of God has not been upon their wills and minds and affections rightly to subdue them to the grace of the gospel. Therefore also such persons, upon the withdrawing of those influences that at present are mighty upon them, do forthwith forget both what they had and what work it made upon them. Straightway they forget what manner of men they were. It is said of Israel, "They sang his praises; they soon forgat his word." So these; they forget. They forget what light and what convictions they had. They forget what sorrow for sin they had. They forget what tastes of Christ and his word they had. They forget what joy and comfort they had. They forget how fair for heaven they were. And they forget how cleansed once they were. "They have forgotten that they were purged from their old sins." 2 Pet. 1:9. Now, forgetfulness makes things that are past as nothings; and if so, then it can lay no obligations upon the mind to engage it to delight in them; no, not in thoughts of them, as if they were remembered by us. Forgetfulness is a very dangerous thing; it makes preaching vain, profession vain, faith vain, and all to no purpose. 1 Cor. 15:1, 2. Such profession is but a dream; and such professors but as dreamers; all vanishes in the morning. This made Paul so caution the Corinthians that they should forget not the preaching; arid the writer to the Hebrews so earnestly call them, in their backsliding, back to the remembrance of former days, and to the recollecting what it was that then made them so willingly endure their great fight of affliction. Forgetfulness, I say, makes things nothings; it makes us as if things had never been; and so takes away from the soul one great means of stay, support, and encouragement. When choice David was dejected, the remembrance of the hill Hermon was his stay; when he was to go out against Goliath, the remembrance of the lion and the bear was his support; so when those that have had the power of the things of God upon them, can think of this when they are withdrawn, it will, even the thinking of it, have some kind of operation upon the soul. And therefore you shall find, that the recovering of a backslider usually begins at the remembrance of former things. "Remember from whence thou art fallen, and repent and do thy first works."
