So as it relates to the OP, how do you as you are right now, know that you are not an atheist turned Christian? You certainly cannot predict the future. The current atheist who 10 years ago claimed to be saved and practiced everything mentioned in this thread as evidence they were saved, just didn't realize that they were not actually saved?Impossible they were never of us for if they were of us they would of never left us. Read about that truth in 1 John.
No such thing as a Christian turned atheist only an atheist turn Christian.
any ore oxymorons for us today ?
hope this helps !!!
