The giant’s incredible size loomed over the valley as he hurled his insults toward the armies of Israel. He was a champion among the Philistine warriors, and everyone knew why: he was huge! Several feet taller than the average man, no one could hope to survive hand-to-hand combat with Goliath of Gath. No one, that is, except a youngster named David. Armed with faith in God, David displayed remarkable courage as he first challenged and then defeated the giant. His confrontation with Goliath is an impressive display of faith, courage, conviction, and the victory God gives those who rely on Him (read 1 Samuel 17). David’s brothers scolded him for talking about doing battle against the giant. His response, “Is there not a cause?” resounds today (1 Sam. 17:29). Enemies to the faith exist, the cause for battle remains (2 Cor. 10:3-6). (1) False doctrine is a mighty giant we must battle. Contending for the faith is not fashionable to many Christians, yet the cause exists (Jude 3-4). (2) Worldliness is a formidable giant we must battle. Every day, the world defies the armies of the living God (1 John 2:15-17). (3) Complacency is a dangerous giant we must battle. Apathy is an intimidating opponent we must slay with fervent zeal to do the will of Christ (Heb. 6:11; Rom. 12:11). Faith overcomes evil giants that oppose the living God (1 John 5:4). Christians must fight the good fight of faith (1 Tim. 6:12). Take up the whole armor of God and trust God’s victory through the power of Christ (Eph. 6:10-13, 17). Soldiers of Christ, arise. The cause is great, but our God is greater (Rom. 8:37).
