If you are confessing your "sins" to make it into a paradise earth then you are doing it for the wrong reason. You wouldn't survive this system because of that act alone.
If the Bible is true then you must love God and you must have faith in him. Keeping your eye on the prize isn't really love for God.
It's a lose, lose situation for you right now. You obviously fear the wrath of the end of the world but you have no love for the God you learned about.
I guess you to ask yourself the following questions...
Am I going to try my best to learn how to worship God appropriately? AND
Do I really believe in a religion that teaches that the only way to God is through Jesus and the WBTS rather than just Jesus? AND
Do I really believe in God at all? AND
Is the appeal of religion to me just the reward of an afterlife?
And by the way, you can only be an apostate if you know the truth exactly (without doubts) and try and pull others out.
