Who will be in hell?  Unusual question, but a good question to ask.  Of course, Satan and all his angels will be there (Matthew 25:41).  Hell will be filled with those who know not God and do not obey the gospel of Christ (II Thessalonians 1:8), with backsliding Christians (II Peter 2:20-22), with those who are lukewarm (Revelation 3:16), with the immoral (I Corinthians 6:9-10), with the fearful (Revelation 21:8).  In fact, most people will spend an eternity in hell (Matthew 7:13-14).  But you CAN avoid hell by repenting of your sins (Acts 17:30) confessing your faith in Christ (Acts 8:37) being baptized into Christ in order to receive the forgiveness of your sins (Acts 2:38) and living a life of faithful service to God (I Corinthians 15:58).
