I appreciate your perspective Mike. I disagree with much of it, and some of what you say doesn't accurately reflect what I believe or what my religion teaches, but I have no desire to attempt to broadly discuss those topics here. So I will just say a couple of simple things, and leave it at that.
The price of entry is your best, not perfection. That is the point of Christ and his atonement. He can and will make up the difference.
Family is still family on the other side. They still care and still watch. But as you say, they have greater understanding meaning they can witness our ups and downs from a different perspective than us. Besides, I believe they have other things to occupy them, so, much like here on Earth, they might check in, but they aren't watching our lives like a TV show.
I find the statement that "life is meaningless" sad. I don't really care if my beliefs are wrong and there is no afterlife. Believing that there can be more causes me to reflect on who and what I am, and who and what I can be. It leads me to desire to improve myself and strive (and fail) for general kindness overall. It takes me away from the most basic way of living, all wrapped in up "what do I want", and causes me to consider things much greater than just my own needs. These are things I think are lacking today in society, and I will not regret choosing a belief system that combats them, even if my beliefs were proved frivolous. I don't believe in the meaningless of it all. I believe I am improved by my belief in something greater.
If you want to discuss further how religion has improved my life, I'm happy to do so more privately. Feel free to PM me if you are interested.
