This is actually a very personal story. It is personal to David who doesn't like Goliath speaking that way to the army of God. David especially doesn't like the way Goliath insults God. Goliath doesn't like the way, at first, no one does anything. Then to add insult to injury they send a "boy" to fight him. This makes Goliath angry so he shouts more insults.
It is personal to us, also, because we hear OUR giants shouting at each of us too. We need, like David, to face our "giants." We need to remember that God IS with us. David pointed out that God had protected him (David) when facing lions and bears AND God would protect him as he faced Goliath. God was with David, God has been with us AND God IS with us. We can face our giant(s) too!
What giant are you facing? The fear of things changing? The phone call you did NOT want to get? The diagnosis that is not only not good but also scary? Or, like me, knowing that God is calling us to new things -- that can be very scary!
Remember, like my friend Isaiah says (41:10 & 13), God not only holds us in God's hand God has US by the hand leading us. God IS with us! Emmanuel -- God IN us, WITH us AND guiding us. Feel God's arms wrapped around you, holding you and guiding you as you face your giant(s).
