Gideon was told to rescue Israel from the Midianites (whose name means strife and contention). Against overwhelming odds, Gideon's army won. (Judges chapters 6 & 7).
Elijah stood alone against 850 false prophets on Mt. Carmel. God proved that one true voice will silence the multitude of lies. (1 Kings chapter 18).
The entire Israelite army was cowering in fear before the giant Goliath, until one young man dared to face him down in the power of the Almighty God.
David replied to the giant, "You come to me with sword, spear, and javelin, but I come to you in the name of the LORD of Heaven's Armies—the God of the armies of Israel, whom you have defied. 1 Samuel 17:45 NLT
So David triumphed over the Philistine with only a sling and a stone, for he had no sword. 1 Samuel 17:50 NLT
That sling represents a sacrificial life because an animal had to die to produce the leather. As believers today we have an greater arsenal than any of these other champions of the faith. We can stand against our enemies on the basis of a sacrificial life, the Rock, who is Jesus Christ (Yashua) and with the two edged sword, which is the Word of God.
Stand on the Word and pray for the victory.
