Goliath as a type of Satan appears only briefly, at the close of the sermon's call to spiritual warfare. After describing Satan and his demons as formidable, invisible foes who work through people, the sermon assures believers that victory is already secured: Jesus Christ is "our David" who has defeated "their Goliath, Satan," and He lives in believers. The comparison casts Satan as the towering, intimidating enemy whom Christ has already overcome. Yet the victory is not automatic in daily life. Believers must acknowledge that these adversaries are real and give God the chance to defeat them through obedience, putting on the whole armor of God and holding their position against Satan's deceptions of pride, envy, and covetousness.
