The questions surroundings
God & heaven/hell are quite tricky & unnecessary at times.
But hey – They’re asked & the “Bible Christian’s” answer them.
She asked :
Why would God burn his people because he died for their sins ?!
They answered :
God has promised that at the end of the world, every wrong will be atoned for and He will even resurrect dead people to achieve justice. (Heb 10:30, 31; Mat 25:46) Since the fires of Hell will also extract restitution from the devil and his angels, I suppose Hell could last for several days perhaps 40 days and 40 nights? Regardless of how long it takes, everyone in Hell will eventually die and when the wicked no longer exist, Jesus will create a new Heaven and a new Earth.
“Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea [of fire].” (Revelation 21:1)
