Giants fall when fear is rightsized.

1 Sa 17:11 - When Saul and all Israel heard these words of the Philistine, they were dismayed and greatly afraid.

1 Sa 17:24 - All the men of Israel, when they saw the man, fled from him and were much afraid.

1 Sa 17:31-37 - When the words that David spoke were heard, they repeated them before Saul, and he sent for him. And 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 but a youth, and he has been a man of war from his youth.” But David said to Saul, “Your servant used to keep sheep for his father. And when there came a lion, or a bear, and took a lamb from the flock, I went after him and struck him and delivered it out of his mouth. And if he arose against me, I caught him by his beard and struck him and killed him. Your servant has struck down both lions and bears, and this uncircumcised Philistine shall be like one of them, for he has defied the armies of the living God.” And David said, “The Lord who delivered me from the paw of the lion and from the paw of the bear will deliver me from the hand of this Philistine.” And Saul said to David, “Go, and the Lord be with you!”

What a great contrast in their respective responses to fear. Where Saul and the men of Israel responded with fear, David responded with courage and faith in his fear of God. He was more concerned with the glory of God than he was with the fear of man. Though this story is very familiar, there are some great principles to be gleaned from this story. First, remembering is important. David remembered how God came through for him in killing lions and bears, but Saul the men of Israel seemed to forget all that God had done. When we remember the character of God and how he acted and acts on our behalf, it will change our response to difficult and fearful situations. God is both good and in control, He is all powerful and intimately sovereign. Second, it is does matter the size or age or skill to act courageously. God delights in bringing Himself glory and does it more often through weak vessels so there is no question who get the glory. Third, when we fear our heart fails. Fear destroys courage and joy and peace. Fear defeats a person before the thing we fear ever does. When we fight for the glory of God, whether things that directly oppose God or even as simple as doing everything as unto God, we can be confident and courageous in the fear of God.
