Heaven and Hell

Heaven and Hell are very important, it is the reason why we spread the gospel so it is vital that we understand what they are.

Hell
Hell is the place of judgement, where God's wrath falls on those who have not accepted Him and so are cast away from Him. Hell must exist because God is just, there must be punishment for sin. There are many biblical descriptions for hell.;
Matthew 8:12 - Weeping and gnashing of teeth.
Mark 9:43-49 - Fire.
Romans 2:7-9 - Wrath and anger.
2 Thessalonians 1:9 - Everlasting destruction.
Hell is an everlasting death, a spiritual death where you are detached from God.

Heaven
Heaven is to dwell with God, to be in the relationship with Him that He created us for, a good description is found in Revelation 21. Heaven is a spiritual place as can be seen in 2 Corinthians 12:1-3. The Jewish science at the time set the universe in three layers, the first heaven was the sky, the second heaven was the universe and the cosmos and the third heaven is the spiritual realm where God is. To get to hell you merely have to reject God (which we all have done already), to get to heaven, you must place your trust in Jesus Christ. Paul outlines this in Romans 4.
