Take the helmet of salvation and the sword of the Spirit, which is the word of God. Ephesians 6:17 Of all of the pieces of armour, the one we are most experienced with is the helmet. Hockey players, cyclists, snowboarders, rock climbers... we wear a helmet when we engage in these and more. Why wear a helmet? To protect your head, of course. The helmet is a key piece as it protects your skull, your brain, your vision, your thoughts… such a critical component of your body. But why, as a Christian, protect your head? The armour of a warrior is the analogy that Paul uses when he advises Jesus-followers to get ready for the conflicts and battles inevitable in life. The Helmet of Salvation protects our mind, where so many battles take place. 1 Corinthians 2:16 tells us that believers “have the mind of Christ.” 2 Corinthians 10:5 explains that those who are in Christ have divine power to “demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ” The gift of salvation in Jesus Christ is our helmet; when we believe and profess Jesus as our Lord and Savior by grace through faith, we are outfitted with this defensive headpiece. When we are intentionally fixed upon and abiding in Christ, we suit up for battle against the enemy’s schemes and the world’s temptations.
But we must consciously put it on every day to protect our minds and to find our hope and strength. So, we learn Scripture through memory work. We read the Bible in devotions and in Bible class. We pray through and over all things. We wear the armour.
