So can Christians be demon-possessed? No. They are sealed by the Spirit, purchased by the blood, and kept by the power of Christ. Can Christians be influenced? Yes, and Scripture calls us to be sober-minded, to resist, and to stand firm.
The task of the church is to comfort believers with the truth of their security in Christ, and to equip them to recognize and resist the schemes of the enemy. The devil is real, but he is defeated. He still roars, but he roars as one declawed by the cross. And nothing—neither angels nor rulers, nor powers, nor anything in all creation—can separate us from the love of God in Christ Jesus our Lord.
