What gave teenage David the faith to face a giant with nothing but a sling and stones? Faith, through dedication to God’s word, and the Holy Spirit made David bolder than all the soldiers in Isreal’s army. David was considered a misfit because of his youth and physical weakness, so God does not care if you are too short, not smart, poor, or have a stutter. God will not fight through your strength but His own. We must partake in fighting God’s battles instead of God fighting our own battles and meditating on God’s word day and night. If not, we’re lunch for Satan.
