God is capable of doing anything he wants. He is more powerful than anyone or anything. "You come against me with sword and spear and javelin, but I come against you with the name of the Lord Almighty, the God of the armies of Israel, whom you have defied. This day the Lord will deliver you into my hands". (1 Samuel 17:45-46)

When a problem or difficultly or giant comes your way, remember what God has done in the past. "You shall remember the way your God lead you 40 years in the wilderness, remember that you were a slave in Egypt but he brought you out with his mighty hand and his outstretched arm". (Deuteronomy 8:2, 5:15, 7:17-18, Psalm 102:8)

God will use what little you have--your strength, your experience and He will magnify them. "This day the LORD will deliver you into my hands, and I will strike you down and cut off your head. This very day I will give the carcasses of the Philistine army to the birds in the wild animals in the whole world will know that there is a God and Israel". (1 Samuel 17:46; John 6:9)
