It is written: And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever. Revelation 20:10
The Beast{Antichrist} and the False Prophet are still in the Lake of Fire after the 1,000 year reign of Christ, which shows that God will give them bodies that will not persih but will feel the torment and agony of the burning flames of fire which will torment them for all of eternity and all who follow them.
This doesn't have to be so for those who want to avoid it, the gift of God is eternal life through Jesus Christ our LORD who Loved the World so much, And it is given freely by grace to all who is willing to receive it.
I would lay down my life if I was assured that one muslim or one lost sheep would be saved, that is how certain I am of what I speak.
Jesus is coming very soon to take the Faithful{THOSE WHO ARE WASHED IN HIS BLOOD} with Him, will you be part of it?
The Lord knoweth the HEART.
For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God. 1 Corinthians 1:18
God Bless!
