Jesus has a lot to say about the all to real hell==
Matthew 10:28 28Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in
hell.
Matthew 5:29-30 29If your right eye causes you to stumble, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. 30And if your right hand causes you to stumble, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into
hell.
2 Thessalonians 1:8-10 8He will punish those who do not know God and do not obey the gospel of our LORD
Jesus. 9They will be punished with everlasting destruction and shut out from the presence of the LORD and from the glory of his might 10on the day he comes to be glorified in his holy people and to be marveled at among all those who have believed. This includes you, because you believed our testimony to you.
