@cicerone imposter,
YOU say it doesn't exist. Thankfully that does not make it so.
I also live as if today was the last day of my life. My friends and family die around me, I know my day will come too. But the difference is that when I go to heaven and God asks me "What have you done with my Son Jesus Christ?" I want to be able to say. I did everything I could to do what Christ said to do.
" Go into all the world and preach the good news to all creation" and
"whatever you did for one of the least of these brothers of mine, you did for me."
The brothers of mine being the hungry, the thirsty, those in prison etc"
I cannot speak for other Christians and so-called Christians who don't read the bible and know what Christ wants for them.
And I don't know the answers to your last two questions but I will try and find the answers and get back to you. I have never been a military person or an athelete. I've only been a Christian for 7 years and I'm still learning.
