Do you understand the concept or "relativistic time"?
I don’t have a ‘lock’ on scripture and, sorry to burst your bubble, but neither do you, nor does even Billy Graham. In Heaven, I believe there will be so many truths revealed that we will each be in awe for 10,000+ years of Eternity. I am not prepared to get into a long drawn out discussion about time dilation. There are many unexplained issues with the various shades of each THEORY, as there are with the ‘end-times’ THEORIES.
The time spent debating this issue is time spent being side-tracked by the Adversary, time that could be spent in more productive pursuits. If you wish to spend your time debating fellow Christians, rather than sharing the Gospel with others, have at it. I’ve wasted enough time already.
