Why? To give us eternal life. You guys are arguing that everyone has eternal life. Some in paradise, some in agony.
You also are arguing for etenal life for all, however you are also saying that Jesus died for nothing.
This first question I have to ask is if you believe Scripture to be God breathed and without error. If you answer you don’t believe that then the discussion is over because you can make up whatever you please. It is the Gospel according to DManA and I don’t know that one. If you do believe God’s Word as inspired in it’s entirety then it would be impossible to find the concepts of annihilationism or universalism in the Bible.
