“Once you are able to ascribe creation to the Creator (the one spoken of in the Bible), the things that you expressed you do not now know for sure (the existence of heaven, hell, etc.), begin to become knowable.”
Only if you count delusional fantasy as “knowable.” By the way, I used to be a Christian, having been indoctrinated in that sort of thing by well-meaning people. Funny thing is, while I was a believer, I somehow missed out on the secrets of the universe (including hell and heaven) knowledge. Which, by the way, made me start to think about whether people like you who pretend to “know” about God’s little secrets have any clue. It did take me a few years of self-directed “debriefing,” but eventually I did see the light. Now I just laugh at religious folks.
The biblical position on your stated status as a former christian is this: there are no such things as “used to be christians.” People that say they are, were never ones of Christ’s. To be a true christian is to place a God-given, saving faith in the person and finished work of Christ.
What it says about those who once followed, but have turned away is ominous:
“For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost, And have tasted the good word of God, and the powers of the world to come, If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame. (Heb 6:5-6)
For the true christian, the following applies (also from the book of Hebrews):
“Cast not away therefore your confidence, which hath great recompense of reward. For ye have need of patience, that, after ye have done the will of God, ye might receive the promise. For yet, a little while, and he that shall come will come, and will not tarry. Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him. But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.”
Because of these things, I do not laugh at, but rather pity you.
