The story of David and Goliath is a perfect illustration of our daily problems nowadays.
When David came face to face with Goliath in the valley and told him:
"You come at me with sword and spear and battle-ax. I come at you in the name of God-of-the-Angel-Armies, the God of Israel's troops, whom you curse and mock."
You see that Goliath still did not show signs of relaxed, and all that Mr. Big stuff. he still held on to his armor and sword. You don't see him dropping his armor and sword and trying to fight like a man.
That shows us that even though we might be small in front of our problems, but if we have the backup of God almighty, our problems no matter how big they are, they will be afraid of us.
David killed a man almost 4 times his stature and took home the victory. In the same way we can take down out problems and go home victorious
