Charles H. Spurgeon on Psalms 13:1

"How long wilt thou forget me, O Lord?" etc. The departures of God from true believers are never final; they may be tedious, but they are temporary. As the evil spirit is said to depart from Christ for a season (Luke 4:13; though he quitted that temptation, he did not quit his design, so as to tempt no more), so the good Spirit withdraws from those that are Christ's, for a season only, 'tis with a purpose of coming again. When he hath most evidently forsaken, 'tis as unquestionable that sooner or later he will return; and the happiness of his return will richly recompense for the sadness of his desertion; Isaiah 54:7, "For a small moment have I forsaken thee; but with great mercies will I gather thee;" here is not only a gathering after a forsaking, but "great mercies" to make amends for "a small moment." He who hath engaged to be our God for ever, cannot depart for ever. Timothy Cruso, 1696.
