As Christians, we are involved in a battle. Our arch-enemy is Satan who “walks about like a roaring lion, seeking whom he may devour” (1 Peter 5:8). The way in which he devours unwary people is by tempting them to sin – by convincing them that sin is a more rewarding master than Christ. He therefore disguises himself and his agents, and he makes the pleasures of sin appear very appealing to us. And Satan does not just attack us from the front where we can clearly see him coming; he attacks from every side.
