1 SAMUEL 17:32-37 “Then David said to Saul, “Let no man’s heart fail because of him; your servant will go and fight with this Philistine.” And Saul said to David, “You are not able to go against this Philistine to fight with him; for you are a youth, and he a man of war from his youth.” But David said to Saul, “Your servant used to keep his father’s sheep, and when a lion or a bear came and took a lamb out of the flock, I went out after it and struck it, and delivered the lamb from its mouth; and when it arose against me, I caught it by its beard, and struck and killed it. Your servant has killed both lion and bear; and this uncircumcised Philistine will be like one of them, seeing he has defied the armies of the living God.” Moreover David said, “The Lord, who delivered me from the paw of the lion and from the paw of the bear, He will deliver me from the hand of this Philistine.” (NKJV)
One important aspect we can learn from the incident between David and Goliath is that David never allowed doubts to settle in his mind even when the people around him had great doubts. He knew that God wanted him to face the giant Goliath and that God would help him in defeating the giant. When David asked Saul to let him face the giant, Saul must have stood astonished and doubted how will this teenager who never fought a battle in his life, fight Goliath, a nine foot tall, veteran of many battles.
Saul must have responded, “You can’t do it. You’re only a boy, and you’re too small, you don’t have enough experience.” When you decide to face your giants, there are always going to be doubters around you. They will tell you “it’s impossible, you can’t do it, don’t waste your time, don’t even try it.” You might even have these doubts running in your head. Don’t listen to them. David didn’t let a doubt get in his way. He continued to convince Saul that he could do it, just like how God helped him defeat the bear and the lion while he was shepherding.
When God has called you to face your giant, you shouldn’t allow doubts to sway you. You need to look through eyes of faith to what God can do. Look to God and not to the giant you face or even your own abilities. For it is God’s will for you to face the giant and when you take the step of faith He will help you defeat the giant.
