Yes, the Bible certainly does tell us about the devil and what he wants to accomplish in the world -- and also in our lives. The devil is real, and you can be sure he's always at work, diligently seeking to achieve his goal.
What is his goal? His goal is nothing less than opposing God in every way he possibly can. God's goal is to turn us away from sin and make us more like Christ -- but Satan's goal is exactly the opposite. He wants to keep us under sin's control, and turn our hearts away from God. This is why the Bible calls him "your enemy," and says he is "like a roaring lion looking for someone to devour" (1 Peter 5:8).
Sometimes Satan's attacks are very open and obvious, tempting us to do evil things that sound exciting -- but will always bring us to destruction. But often his attacks are very indirect and subtle, and we may not even realize what he is doing. The Bible even warns us that at times "Satan himself masquerades as an angel of light" (2 Corinthians 11:14). But his goal remains the same: to keep us from God and His will for our lives.
How can we gain victory over Satan? The best way is to stay close to Christ. He is stronger than Satan. Some day, Christ's victory will be complete, and Satan and all his evil works will be banished forever. Is Jesus Christ the center of your life?
