What does the bible have to say about hell?

The Bible describes hell as a place initially prepared for Satan and his demons, who had rebelled against God. 

It also mentions that hell is a place of constant torment and is the destiny of all non-believers. 

More importantly, those in hell will be cut from the presence of the Lord and an intimate union with Him.

2 Thessalonians 1:9 (NKJV) 

These shall be punished with everlasting destruction from the presence of the Lord and from the glory of His power,

Furthermore, there is a gradation of punishment for those who experience hell as a result of not believing in Christ, and will be without excuse as stated in Romans:

Romans 1:20 (NKJV)

For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse,

In conclusion, this biblical understanding of hell can be defined as follows: Hell is an eternal place of torment whereby God’s justifiable wrath is poured out on Satan, his demons, and un-repented sinners. 

However, in light of this awful reality, there is hope for everyone through Jesus Christ: 

Romans 6:23 (NKJV)

For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.

Although the reality of hell is daunting, the grace of God is equally overwhelming. 

God wants you to spend eternity with Him in Heaven, and all He asks is for you to surrender your life, your ways, and your will to Him, and He promises that your soul will be secured for all eternity through His Son Jesus Christ.
