The being we know as Satan the Devil began his life as a glorious cherub covering God's throne. Before he sinned, this archangel, Hêlêl (“shining one”), had everything going for him. God had created him perfect, wise, and beautiful. He had astounding skills and talents, especially musical talents, which were probably used in praising God. He was given high position as “the anointed cherub who covers” (emphasis ours), meaning that his wings stretched over God's throne. Always at the hub of God's activity, Hêlêl was the perfect specimen of creation—beautiful, wise, talented, skilled, and eminent. Then he spoiled it all through sin.
