I truly do commend you for expressing an interest to learn the truth about this important matter, however, as you can see, that is if you've read the things that have already been written by others, it can be extremely difficult, if not altogether impossible, to "weed" through it all and be successful in arriving at a definitive, scriptural-based understanding. If I could but offer this bit of advise: Always confirm the words of others, and that includes yours truly, with that which the sacred written word of God reveals about matters of importance such as that being discussed here.
