"And whosoever was not found written in the book of life was cast into the lake of fire."
A clear warning. It does not matter if you believe it. Why should I and all others believe you instead of the words of God? The scriptures say this, you say something else. We will go with the scriptures.
You cannot win. You will die and be cast in the lake of fire in due time. So read Romans chapters 1-4 from the King James Bible the Pure Cambridge Edition.
