I just found some verses speaking about the lake of fire.
Revelation 19:20 "Then the beast was captured, and with him the false prophet who worked signs in his presence, by which he deceived those who received the mark of the beast and those who worshipped his image. These were cast alive into the lake of fire burning with brimstone."
Revelation 20:10 "The devil, who deceived them, was cast into the lake of fire and brimstone where the beast and the false prophet are. And they will be tormented day and night forever and ever."
Revelation 20:14
Revelation 20:15
"And anyone not found written in the Book of Life was cast into the lake of fire"
I found these verses and then I saw that the devil was cast there, but also those who are not written in the book. So my question is: are there two lakes of fire? Because we see that not only the devil ended there. I'm not being hateful, pessimistic, bitter or trying to scare anybody. I am just stating what I believe and I think I need to say it. I think is worth considering this too. As a warning. I am open to receive a correction. From God aswell. At the end isn't it such a great love that saves us from such a horrible place. There is shown how great is His love. Being ready to die for us so that whoever believes can escape the condemnation. God doesn't want people to go to hell, that's not His desire. So He tries everything possible to stop them.
You can also read Matthew 25:41
As I was stating before in some of my previous posts, God sometimes does things because of His nature of doing, not because he just decides things. He is not like a man. He is also a loving father aswell. With a mercy way higher than ours. I am just stating what I believe. I am just being open about it. Many things we can not an we will not understand, but one day we hope everything will be revealed.
