No doctrine appears more horrid to Christians and non-Christians alike as the doctrine of Hell, the belief in eternal, conscious punishment against sin. However, despite the efforts of many to dismiss the doctrine, the Biblical testimony is clear. Why is Hell so common in the Bible? Why does Jesus talk about Hell so often? In this short book, we will take a stark look at what the Bible says about Hell as retribution-punishment against sin. More importantly, we will see why this doctrine matters. It matters because only in light of Hell do we understand the Cross of Christ. Hell is a revelation of God-of His mercy, love, and justice. Finally, Hell reminds us that we are surrounded by many who will die and face Hell if they do not believe in Jesus Christ and receive the mercy of God offered through Him.
