"And David girded his sword upon his armor, and he assayed to go; for he had not proved it. And David said unto Saul, I cannot go with these; for I have not proved them. And David put them off him." Happy deliverance from the trammels of human policy! It has been observed, and most truly so, that David's trial was not when he met the giant, in actual conflict, but when he was tempted to use Saul's armor. Had the enemy succeeded in inducing him to go with that, all was gone; but, through grace, he rejected it, and thus left himself entirely in the Lord's hands, and we know what security he found there. This is faith. It leaves itself in God's hand.[13]
[13] How often it happens that the child of God or the servant of Christ, harnessed with human devices for his work, finds himself burdened and hampered with these trammels to obedience and faith. Let them be but shaken off, through grace, and the soul cast upon God finds at once the joy and liberty for the service and energy of faith. [Ed.]
And, my reader, may we not apply this with much profit to the case of a poor helpless sinner in reference to the forgiveness of his sins? I believe we may. Satan will tempt such an one to seek some addition to the finished work of Christ--something that will detract from the glory of the Son of God as the _only_ Saviour of sinners. Now to such I would say, It matters not _what_ you add to the work of Christ,--you make it of no avail. If it might be permitted to add anything, surely circumcision would have been admitted, as being an ordinance of divine institution; yet the apostle says, "Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing. For I testify again to every man that is circumcised, that he is a debtor to do the whole law. Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace." (Gal. v. 2-4) In a word, then, we must have Christ _alone_; we want no more, we can do with no less. If our works are to be put in with Christ's, then He is not sufficient. We dishonor the sufficiency of His atonement if we seek to connect aught of our own with it, just as David would have dishonored the Lord by going forth to meet the Philistine champion in Saul's armor. Doubtless many a so-called prudent man would have condemned what seemed to him to be the rashness and fool-hardiness of the stripling; indeed, the more practised a man was in human warfare, the more likely would he have been to condemn the course adopted by the man of faith. But what of that? David knew in whom he had believed; he knew it was not rashness that was leading him on, but simple faith in God's willingness and ability to meet him in his need. Few, perhaps, in Saul's army knew the weakness of David as realized by himself in that trying moment. Though all eyes were fastened upon him as one having much self-confidence, yet we know what it was that buoyed up his heart, and gave firmness to his step as he went forth to meet the terrible foe. We know that the power of God was there just as manifestly as when the waters of the sea were divided to make a way for the ransomed to pass over; and when faith brings the power of God into action, nothing can stand in the way.
Verse 40 shows us David's armor. "And he took his staff in his hand, and chose him five smooth stones out of the brook, and put them in a shepherd's bag which he had, even in a scrip; and his sling was in his hand: and he drew near to the Philistine." So, we see, David did use means; but what means! What contempt does David cast upon the ponderous armor of his enemy! How his sling must have contrasted with Goliath's spear like a weaver's beam! In fact, David could not have inflicted a deeper wound upon the Philistine's pride than by coming against him with such weapons. Goliath felt this. "Am I a dog?" said he. It mattered not, in the judgment of faith, what he was, dog or giant; he was an enemy of the people of God, and David was meeting him with the weapons of faith. "Then said David to the Philistine, Thou comest to me with a sword, and with a spear, and with a shield: but I come to thee in the name of the Lord of hosts, the God of the armies of Israel, whom thou hast defied. This day will the Lord deliver thee into my hand ... that all the earth may know that there is a God in Israel. And all this assembly shall know that _the Lord saveth not with sword and spear_: for the battle is the Lord's, and He will give you into our hands."[14] Here we have the true object of the man of faith, viz., that Israel and all the earth might have a glorious testimony to the power and presence of God in the midst of His people. If David had used Saul's armor it would not have been known that the Lord saved not by sword and spear--his warfare would just seem like any other; but the sling and the stone while giving little prominence to him that used it, gave the glory to Him from whom the victory came.[15]
