45 Then David said 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. 46 This day will the LORD deliver thee into mine hand...that all the earth may know that there is a God in Israel. 47 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. (1 Samuel 17:45-47)
A sling, a stone and a slap from God was all it took for David the shepherd boy to slay the 9 foot tall Goliath. Incredible isn't it? Not so incredible though when we consider that the hand of God was involved in this feat. I love this story (1 Samuel 17) about how God can take an ordinary person with a heart to serve Him and accomplish the extraordinary. Have you given thought as to the extraordinary thing that God wants you to be a part of? Maybe you just haven't stumbled upon it yet.
I don't think that David planned on killing a giant that day. He was just obeying his father by taking food to his brothers when David heard the taunting words of Goliath the Philistine. I believe that David was a little bit irked upon hearing Goliath's trash talk. David was upset that Goliath was bad mouthing God's armies.
...for who is this uncircumcised Philistine, that he should defy the armies of the living God? (1 Sam 17:26)
I believe that David was prompted by his love for God to fight the giant. However, I also believe that David's biggest opposition in the battle was not Goliath, but the people who were supposedly on his "team". How sad but true that this is often the case when we seek out to do something for God. Have you had this happen to you? If this happens, we can "fight" back, knowing that God is on our side, when we are truly attempting to fulfill God's will in our lives. Let's look at some principles from this chapter:
1) Our motives might be questioned. David's motive's were questioned by his own family. (1 Sam 17:28) but we saw that David's motives were pure in that he was just obeying his father by coming to the battle. If we know that our motives are pure, we don't really have to have the approval of anyone else but God. God knows our hearts.
2) Our qualifications might be questioned. David was a nobody - a shepherd boy. However he was a somebody in God's eyes. Saul was doubtful that David could accomplish the task (1 Sam 17:33) and made sure that David knew of his doubt. However, David was quick to draw on his past successes (slaying a lion and a bear - v 35-35) so that his confidence was not brought down by Saul's disbelief.
3) Our methods might be questioned. David didn't want to fight the giant with traditional armor that he had never used before. Saul obviously thought that David was ill-equipped with the sling and stone so he gave David his own armor to use. (v 38-39) What Saul didn't understand - and he'd been struggling with this for awhile - was that God's power was sufficient to get the job done. David understood fully that the source of his strength was God and was willing to give God all of the credit for his success.
We all know the end of the story, don't we? David won and Goliath lost his head...literally. If God is on our side, no one can prevail against us. Our negative thoughts cannot win. Others negative thoughts cannot win. God can and will overcome because after all, He can best prove He is God when we give over complete control to Him. What is the "Goliath" in your life? Is it a new ministry opportunity? A new job opportunity? A challenge at home? Remember Who you are to please, remember your past victories, and remember that God is your chief resource.
