(John 3:16-18 NIV) "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
(John 5:28-29 NIV) "Do not be amazed at this, for a time is coming when all who are in their graves will hear his voice {29} and come out--those who have done good will rise to live, and those who have done evil will rise to be condemned.
These are general statements of Jesus. There are other places in the Bible that give some sequences of events but even these are not detailed. One cannot find a checklist in the Bible and say "This year we are on step five of the countdown, etc."
Most of the New Testament gives us direction for living our life now, with the Gospel being our written guide, without being heavy on holding out heaven as a carrot and hell as a threat.
Still, whether we are enjoying the prime of life and health, or the twilight of life and ailments, it is natural for Bible-believing Christians to wonder about what happens after this journey in physical life is over.
I think I have a perspective that is a bit different from many because of my physics background. Physicists realize that we do not directly experience much of the world we study. For example, we cannot experience electricity from the electron's point of view. When we explore entities that we cannot touch or see, we have, what noted Christian apologist R. C. Sproul calls a "discontinuity between experiences". Whenever we have a discontinuity between experiences, we use analogies to describe what is going on. In the case of electricity, for example, we may draw an analogy between the flow of electrons in a wire and the flow of water in a pipe. The reality is very different from the analogy.
We have not experienced eternal life. It is, for us, the quintessential "discontinuity between experiences". To describe eternity, requires we use our present language and analogies that pertain to time, space, and matter to describe that which is not time, space, and matter. In short, we are forced to use the temporal to describe the eternal. The reality is very different from the analogy.
It is pointless to argue over whose eternity language or eternity analogy is "right" unless that description somehow distorts the gospel of Jesus Christ. The old Worldwide Church of God erred, not so much in the points of our eternity analogy, but in our arrogance.
