David had faith in God that he is and will always be with him,when the champion named goliath was ridiculing his God,he became revolted and used his faith in the name of the Lord and delt with the situation right there,without the weapons of this world he killed the giant called goliath,he depended on his faith in the Lord.
Today if you are facing a giant(a difficult situation)you too can use your faith to overcome your problem by not accepting it instead be revolted against it like David and God's name will be glorified,he said "You come against me with sword and spear and javelin,but I come against in the name of the Lord almighty"
You can if you believe!
(1samuel 17:45 niv)
