We begin this survey with negative examples. In order to discover the faith God accepts, we will look first at forms of faith that God rebukes and rejects.
Does Satan believe in God? Even as a fallen creature, Satan used to come into the presence of God (Job 1:6; 2:1). Satan knows more about God and His glory than any believer on earth! The demons under him also know of God and His Son (Matthew 8:29; Mark 1:24; 3:11; Acts 19:15). “You believe that God is one; you do well. Even the demons believe—and shudder” (James 2:19). No, the problem of Satan and his spirits is not one of unbelief. Their problem is the sin of rebellion despite all that they know and believe.
God did not spare angels when they sinned, but cast them into hell and committed them to chains of gloomy darkness to be kept until the judgment (2 Peter 2:4 cf. Jude 6).
