Surging forward with a shout

we are like the armies of Israel who, after the giant Goliath fell dead before David, "surged forward with a shout" (1 Sam. 17:52, NIV). We do not defeat the giant for ourselves, nor do we establish God's kingdom in our power. But having already witnessed the victory, we are called to "surge forward" and join the fight.
