God has equipped us with both spiritual armor and access to His presence. We are called to “put on the full armor of God so that [we] can stand against the schemes of the devil” (Ephesians 6:11). We simply cannot fight this battle without biblical truth and prayer, but the good news of the gospel is that we have been given access to God’s Word and His throne of grace, before which even the most weary and defeated disciple can fall and find help.
We often remember great battles by where they were fought: Gettysburg, Helm’s Deep, Pearl Harbor. But the battles were not ultimately about those places; they were about a greater desire, a deeper principle. The same is true about spiritual warfare. Our hearts are where spiritual battles are fought, but the aim of the devil’s warring isn’t ultimately about us. What is he after? God’s glory. It’s always been this way (Ezekiel 28).
So why are we, humans who are flesh and blood, engaged in conflicts in the spiritual realm? Because, as the Westminster Catechism says, we exist to glorify God and enjoy Him forever, and the devil wants more than anything to render us irrelevant when it comes to living this sort of life.
