An encouraging but often overlooked lesson from the account of David and Goliath is:
Cultural giants aren't as invincible as they seem... and we should not fear them when faced in the power of the living God.
'Then David said to the Philistine, “You come to me with a sword and with a spear and with a javelin, but I come to you in the name of the LORD of hosts, the God of the armies of Israel, whom you have defied"' (1 Sam.17:45).
