Peter wrote, "Be watchful, your adversary the devil prowls like a roaring lion," as a man who learned that lesson the hard way, around a charcoal fire on the worst night of his life. Most Christians know the devil is real, but very few have seriously studied how he actually works, and in this message from scar tissue we pull back the curtain on his oldest strategies, his most dangerous disguises, and the one weapon that stops him cold.
