Answer
Ephesians 6:17 instructs us to put on the whole armor of God and to “take the helmet of salvation and the sword of the Spirit, which is the word of God.” When a soldier suited up for battle, the helmet was the last piece of armor to go on. It was the final act of readiness in preparation for combat. A helmet was vital for survival, protecting the brain, the command station for the rest of the body. If the head was badly damaged, the rest of the armor would be of little use.
The assurance of salvation is our impenetrable defense against anything the enemy throws at us. Jesus said, “Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in hell” (Matthew 10:28). The idea in this verse is that, as we prepare for Satan’s attacks, we must grab that helmet and buckle it on tightly. Salvation is not limited to a one-time act of the past or even a future hope. God’s salvation is an ongoing, eternal state that His children enjoy in the present. It is daily protection and deliverance from our sin nature and Satan’s schemes.
Because of the power of the cross, our enemy no longer has any hold on us (Romans 6:10; 8:2; 1 Corinthians 1:18). He knows that, but he also knows that most of God’s children do not know that—or, at least, they do not live as if they know. We must learn to keep our helmets buckled so that his fiery missiles do not lodge in our thoughts and set us on fire. Through this helmet of salvation, we can “destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ” (2 Corinthians 10:5).
There are several actions a believer can take to keep this helmet fastened and functioning:
1. Renew our minds. Our minds are battlefields. The outcomes of those battles determine the course of our lives. Romans 12:1–2 instructs us to renew our minds by allowing the truth of God’s Word to wipe out anything contrary to it. Old ideas, opinions, and worldviews must be replaced. We must allow God’s truth to continually wash away the world’s filth, lies, and confusion from our minds and adopt God’s perspective.
2. Reject doubts that arise from circumstances. Human beings are sensory creatures. What we cannot fathom with our five senses, we tend to disregard. If we allow them to, circumstances may convince us that God does not really love us or that His Word is not true. It is impossible to have faith and doubt at the same time. God rewards our faith. With the helmet of salvation firmly in place, we can choose to believe what appears impossible (Hebrews 11:6; 1 Peter 1:8–9).
3. Keep an eternal perspective. When life crashes in around us, we must remember to look up. Our salvation is the most precious gift we have received. Keeping our eyes on that can help us weather life’s storms. We can choose to live our lives by the motto: “If it doesn’t have eternal significance, it’s not important” (see Matthew 6:20; 1 Corinthians 3:11–13).
4. Remember that victory is already accomplished. When we consider ourselves “dead to sin but alive to God” (Romans 6:11), we eliminate many of the opportunities Satan uses to entrap us. When choosing sin is no longer an option for us because we recognize ourselves to be “new creatures” (2 Corinthians 5:17; 1 John 3:9), we effectively cut off many avenues of failure.
5. Find all our hope in Him. Psalm 73:25 says, “Whom have I in heaven but You? Besides you, I desire nothing on earth.” Our helmet is most effective when we treasure what it represents. The salvation Jesus purchased for us cannot share the place of importance in our hearts with earthly things. When pleasing the Lord is our supreme delight, we eliminate many of Satan’s lures and render his evil suggestions powerless.
As we wear the helmet of salvation every day, our minds become more insulated against the suggestions, desires, and traps the enemy lays for us. We choose to guard our minds from excessive worldly influence and instead think on things that honor Christ (Philippians 4:8). In doing so, we wear our salvation as a protective helmet that will “guard our hearts and minds in Christ Jesus” (Philippians 4:7; cf. Isaiah 26:3; 1 Peter 1:5).
