The Life and Times of

Truth #4: You must prepare before you meet your giants.

(1 Sam 17:31-39) "What David said was overheard and reported to Saul, and Saul sent for him. {32} David said to Saul, "Let no one lose heart on account of this Philistine; your servant will go and fight him." {33} Saul replied, "You are not able to go out against this Philistine and fight him; you are only a boy, and he has been a fighting man from his youth." {34} But David said to Saul, "Your servant has been keeping his father's sheep. When a lion or a bear came and carried off a sheep from the flock, {35} I went after it, struck it and rescued the sheep from its mouth. When it turned on me, I seized it by its hair, struck it and killed it. {36} Your servant has killed both the lion and the bear; this uncircumcised Philistine will be like one of them, because he has defied the armies of the living God. {37} The LORD who delivered me from the paw of the lion and the paw of the bear will deliver me from the hand of this Philistine." Saul said to David, "Go, and the LORD be with you." {38} Then Saul dressed David in his own tunic. He put a coat of armor on him and a bronze helmet on his head. {39} David fastened on his sword over the tunic and tried walking around, because he was not used to them. "I cannot go in these," he said to Saul, "because I am not used to them." So he took them off."
If Eliab has his way, David will be sent away in shame. Fortunately for Israel, David is neither devastated nor deterred by Eliab’s sarcastic rebuke by which he attempts to “cut David down to size.” Eliab may have ordered David to go home, if Saul had not gotten word about David’s interest in his incentive program for taking on Goliath.
Regardless, Saul summons David, whose first words to his king are gracious and encouraging:

32 “Let no man's heart fail on account of him; your servant will go and fight with this Philistine”.
While the application of David’s words goes beyond Saul, it certainly focuses upon Saul who is terrified by the foreboding presence of Goliath and the Philistines. David graciously and somewhat indirectly encourages Saul not to fear. The reason David can say this is because he is willing to go and fight Goliath. David is willing to do what neither Saul nor any other soldier in Israel is willing to do – fight Goliath.
Before considering David’s faith, let us ponder Saul’s fears for a moment. I have to conclude that by nature Saul is less than courageous. His father was a “mighty man of valor” (9:1), but this is never said of Saul.⁶ Saul is the one who hides in the baggage when he is indicated to be Israel’s king (10:22). When the Spirit comes upon Saul, he becomes a new man, with a new heart (10:9).
David seems to be a man after God’s own heart before the Spirit comes upon him. When faced with Philistine opposition, Saul is passive, not aggressive, though fighting the Philistines is a significant part of his calling as king (9:16). Only when the Spirit comes upon Saul mightily does he seem to act decisively against his enemies (11:6). By nature, Saul is less than courageous; only in the Spirit is he a true leader.
Having said all of this, I must admit feeling some compassion (or at least pity) for Saul. In many ways, his refusal to fight Goliath (individually or collectively) is completely logical. After all, Saul has been told that his kingdom is as good as finished (13:13-14; 15:23). Samuel leaves him, never to see his face again (15:35). And the Spirit of God has departed from him, replaced by an “evil Spirit from the Lord” (16:14). I don’t think I would be doing anything dangerous or courageous either.
David is a man of courage and, at this point, the only Israelite on the battlefield with courage. Where does he get this courage? Let me suggest several sources. First, David’s courage grows out of his theology – his understanding of God. David is “a man after God’s own heart” (13:14; 16:7). A person cannot be a “man after God’s own heart” unless he knows the heart of God, and this comes through an understanding of God through His Word (see, for example, Psalm 119). David knows God, not only historically (the way God delivered Israel in the past), and theologically, but experientially, as he will soon indicate to Saul.
David acts like the king of Israel should act. He needs to trust in God, to inspire his fellow-Israelites to do likewise, and to defeat the enemies of God, especially the Philistines. When David was anointed as the coming king over Israel (chapter 16), he must have spent a good deal of time pondering just what all this meant, much like Mary would do centuries later (see Luke 2:19, 51). What does it mean to be Israel’s king? What should David do as the king? No doubt his actions the day he faces Goliath are the result of his meditations. This young man is not a soldier, and some would say he is too young to fight, but David is providentially placed in a circumstance where he must trust God and obey His Word or cower in unbelief and disobedience, as Saul and the rest.
Saul gives David every opportunity to excuse himself and go back home to his father and his sheep without guilt or shame. There is a certain kindness in Saul’s words to David when he attempts to talk him out of fighting Goliath. Saul does not say that David is too small to fight Goliath, but that he is too young and therefore inexperienced. Goliath is a seasoned champion with years of combat experience behind him. David is but a youth, with no combat missions at all. At least this is what Saul supposes, but David proves otherwise so convincingly that Saul allows him to represent Israel in fighting Goliath.
David is young, but his seemingly trivial duty of caring for a small flock of sheep has very nicely prepared him to fight Goliath. Eliab was never more wrong than he was about David, as David’s words to Saul show. David sees and hears what every other Israelite soldier does that morning on the front lines with his brothers. The difference is that David views this circumstance as amazingly similar to situations he has successfully faced as a shepherd boy. Is Goliath strong and mighty, able to destroy a man? So are lions and bears, and David has faced them down and killed them. Is Goliath an arrogant loud mouth? Few creatures are more intimidating by their roaring than a bear or a lion (see 1 Peter 5:8). In the carrying out of his duties as a shepherd, David has killed both lions and bears (verses 34-36).⁷

Truth #5: Prepare the best you can and depend on God.

As David risks his life to rescue the sheep under his care, God rescues him. Is David worried about facing Goliath? No, because the God who rescued him from the paw⁸ of the lion and the paw of the bear will rescue him from the hand of Goliath. Notice that David speaks of being rescued from the “hand” or “paw” of the lion and the bear, and not the “jaws.”

This is because the wild beast had a lamb in its mouth and refused to release it, so it had to fight David with its paws and claws. Goliath poses no new threat, and since David has, with the help of God, destroyed loud-mouthed lions and bears by his hand, he can also destroy loud-mouthed Philistines. Does Goliath speak (roar) in a way that frightens the Israelite forces? He does not frighten David. He has been here before.
I believe David’s faith in God is contagious, and that Saul somehow believes there is a good chance David will prevail over Goliath. Saul gives David permission to fight Goliath and offers him his armor. The armor is a bad idea, which David rejects, but it does strongly imply that David is fighting Goliath in Saul’s place as the official representative of the Israelite army. If this is the case, then David’s victory should be Israel’s victory (which it proves to be). On the flip side, David’s defeat will appear to be Israel’s defeat, at least by the terms Goliath lays down (see verses 8-9). David is not fighting this battle alone. He is fighting for God, for Saul, and for the entire nation of Israel.
I am not inclined to make a lot out of Saul’s armor which he offers David. It might seem, at least from a distance (and to those not advised) that it is Saul going out against Goliath. After all, who else has armor like Saul’s? It also suggests that David cannot be that small in size, or the armor would not even fit. David puts it on and then puts it off, because he has not learned to fight in such armor – in his words, he has not “proven it.” David will go against Goliath with the same weapons he has used before, with those God has given him the skill to use.
