I. Note the glowing youthful enthusiasm which dares the conflict. When the Spirit of the Lord left Saul, his courage seems to have gone too, and he is cowed, like the rest, by Goliath. His interview with David shows him as timid and unlike his former self, when he dashed at Nahash and any odds. Now he is hardly to be roused, even by David's contagious boldness, and is full of objections and precautions. The temper of the two, as they front each other in Saul's tent, shows that the one has lost, and the other received, the Spirit which strengthens. David has become the encourager, and his cheery words bring some hopefulness to the gloomy, faint-hearted king. The Septuagint has a variant reading in verse 32, which brings this out and suits the context, 'Let not my lord's heart fail.' But, whether this be adopted or no, David appears as quite unaffected by the terror which had unmanned the army, and as bringing a buoyant disregard of the enemy, like a reviving breeze. It was not merely youthful daring, nor foolish under-estimation of the danger, which prompted his stimulating words. The ring of true faith is in them, and they show us how we may surround ourselves with an atmosphere which will keep prevailing faint-heartedness off us, and make us, like Gideon's fleece, impervious to the chill mists of faithless fear which saturate all around. He who trusts in God should be as a pillar of fire, burning bright in the darkness of terror, and making a rallying point for weaker hearts. When panic has seized others, the Christian soul has the more reason for courage. David conquered the temptation to share in the general cowardice, before he conquered Goliath, and perhaps the former fight was the worse of the two.
