Every believer is called to actively participate in spiritual warfare rather than watching from the sidelines. Paul provides three essential commands for spiritual victory: be strong in the Lord's power, put on the full armor of God, and stand firm. Our real enemy isn't other people but spiritual forces led by the devil, who is already defeated through Christ's resurrection. God has equipped us with six pieces of spiritual armor: the belt of truth, breastplate of righteousness, feet prepared with the gospel of peace, shield of faith, helmet of salvation, and sword of the Spirit. We fight from a position of victory, not trying to achieve it, and our job is to stand firm in the battle that Christ has already won.
