Superman is almost unstoppable. I say “almost” because he does have one vulnerability. Kryptonite weakens him, and too much of it can destroy him. Tony Reinke is exactly right when he says, “unbelief is our Kryptonite” (Newton on the Christian Life).
Nothing on earth is more powerful than the Holy Spirit flowing through the faith of a born again disciple of Jesus (1 John 5:4). Nothing. It is the greatest superpower available to anyone anywhere. Through faith nothing is impossible (Matthew 17:20). When a Christian is full of Spirit-empowered faith, he cannot stop and cannot be stopped speaking about what he has seen and heard (Acts 4:20). Not even death can silence him (Hebrews 11:4).
This means that nothing is more humanly destructive to the domain of darkness than a faith-filled Christian. Through him, Jesus destroys the devil’s works (1 John 3:8). The only thing Satan’s forces fear more than the vibrant faith of a Christian is the unified, collaborative, vibrant faith of a community of Christians.
But we do have one vulnerability: unbelief. It weakens us and can destroy us. And Satan knows this very well.
Satan’s After Your Faith
Therefore, Satan’s primary goal in the thousands of his various attacks on us is to take down our faith. His primary goal against the church is to fragment the formidable force of united faith and isolate believers, weakening the church and making individuals more vulnerable (Hebrews 3:12–13, 10:25). His forces are hell-bent on these strategic objectives (Ephesians 6:11–12).
The faith of a Christian is God’s chosen channel to bring his saving, sanctifying, strengthening, healing, and delivering grace to the world. If Satan can weaken our faith, he can immobilize us. If he can destroy our faith, he can destroy us. But if he can’t disarm our faith, Jesus will destroy him through it.
This is why we find the fight of faith and the unity of faith so hard (1 Timothy 6:12; Ephesians 4:13). The stakes are very high in this spiritual war and the battle line is drawn over our faith. Satan is doing everything he can to employ the Kryptonite power of unbelief against us. This is what’s taking place in all our temptations to disobedience, discouragement, doubts, distractions, and divisions. Satan’s trying to weaken and destroy our faith and, through us, the faith of others.
