a kid that he might make merry with his friends; and why? Because he imagined he had earned it. "Lo," says he, "these many years do I serve thee, neither transgressed I at any time thy commandment." Vain man! How could he expect the ring, the robe, or the fatted calf? Had he obtained them, they would have been but the trappings of self-righteousness, and not the ornaments with which grace decks the believing sinner. Thus was it with Saul and David. Saul never knew his need as David knew it, nor have we any record of such flagrant sins in his case; at least, what man would pronounce flagrant. Saul was the outwardly moral and religious man, but, withal, a self-righteous man; hence we have such expressions as these, "I have performed the commandment of the Lord"--"Yea, I have obeyed the voice of the Lord, and have gone the way which the Lord sent me." How could this man value grace? Impossible. A heart unbroken, a conscience unconvinced, can never enter into the meaning of the term Grace. How different was it with David! He felt his sins, groaned under them, confessed them, judged them, in the presence of God whose grace had blotted them all out for ever. There is a great difference between a man ignorant of his sins and walking in self-complacency, and one deeply conscious of his sins, yet happy in the full forgiveness of them. The above train of thought introduces us to the circumstances connected with David in Ziklag of the Philistines--circumstances which fully manifest human infirmity and divine grace and mercy.
