Spiritual warfare isn't about mystical battles with demons, but about spreading the Gospel in a world that opposes truth. Paul concludes Ephesians by teaching that we must rely on God's strength, not our own, to fight for souls. The armor of God - truth, righteousness, readiness, faith, salvation, Scripture, and prayer - equips us to stand against the enemy's schemes. Victory comes through successfully proclaiming the Gospel so others can hear and respond to Christ. We don't fight alone but as part of the body of Christ, encouraging one another in this battle for eternal souls.
