In his collision with Nabal we saw him fail in what seemed one of his strong points--the very spirit of self-control which he had exercised so remarkably toward Saul; and now we see him fail in another of his strong points--the spirit of trust toward God. Could anything show more clearly that even the most eminent graces of the saints spring from no native fountain of goodness within them, but depend on the continuance of their vital fellowship with Him of whom the Psalmist said, "All my springs are in Thee"? (Psalm lxxxvii. 7). Carelessness and prayerlessness interrupt that fellowship; the supply of daily strength ceases to come; temptation arises, and they become weak like other men. "_Abide_ in Me," said our Lord, with special emphasis on the need of permanence in the relation; and the prophet says, "They that wait on the Lord," as a habitual exercise, "shall renew their strength; they shall mount up with wings as eagles; they shall run and not be weary, and they shall walk and not faint." The most strange thing about David's new decline is, that it led him to try a device which he had tried before, and which had proved a great failure. We see him retreating before an enemy he had often conquered; retreating, too, by a path every foot of which he had traversed, and with whose bitter ending he was already familiar. Just as before, his declension begins with distrust; and just as before, dissimulation is the product of the distrustful spirit. He is brought into the most painful dilemma, and into experience of the most grievous disaster; but God, in His infinite mercy, extricates him from the one and enables him to retrieve the other. It is affliction that brings him to his senses and drives him to God; it is the returning spirit of prayer and trust that sustains him in his difficulties, and at last brings to him, from the hand of God, a merciful deliverance from them all.
