The devil, who deceived them, was cast into the lake of fire and brimstone . . . forever. - Revelation 20:10, NKJV
As a girl growing up in western North Carolina, I loved to hike in the mountains. But whenever I set out, my mother’s admonition, “Watch out for snakes!” would ring in my ears. Although I can remember killing only one snake myself, I was present at various times when snakes were killed by others. Each time I observed a fascinating phenomenon. After the snake was killed, its body invariably continued to twitch until sundown. Even though its head was crushed, rendering it powerless, the dead snake’s writhing body was enough to keep me at a distance. After sundown it would finally lie still.
You and I need to remember that ever since the resurrection of Jesus Christ, Satan has been a defeated foe. His head has been crushed. As you and I seek to climb higher in our faith and service and knowledge of God what we are confronted with is merely the twitching of his defeated body. But sundown is coming! One day even the twitching body of that old Serpent, the Devil, will be destroyed.
