“Stay alert! Watch out for your great enemy, the devil. He prowls around like a roaring lion, looking for someone to devour.” – 1 Peter 5:8
The victory of God’s Kingdom is not only future, but a great first victory has taken place. Christ partook of flesh and blood – He became incarnate —
“Because God’s children are human beings—made of flesh and blood—the Son also became flesh and blood. For only as a human being could he die, and only by dying could he break the power of the devil, who had the power of death. Only in this way could he set free all who have lived their lives as slaves to the fear of dying.” – Hebrews 2:14-15
Christ has nullified the power of death; He has also nullified the power of Satan. Satan still goes about like a roaring lion bringing persecution upon God’s people; he insinuates himself like an angel of light into religious circles. But he is a defeated enemy.
