I want to say first that I'm not an official catholic authority. I'm a convert,
Is it suppose to make me feel better to believe in god?
I can't speak for you, I only know what makes ME feel better. Converting to Catholicism has given my life a meaning. It gave me strength to make choices that would create inside of me LIFE instead of DEATH. Before believing, my life was absolute hell, I was unhappy, unfulfilled, I didn't really believe it would get better.
Believing didn't make things all better right away, it helped me to choose life instead of death, positive instead of negative, peaceful instead of self-destructive. Feeling God's love, presence and peace was the reason as to why I turned it around. (My life it is)
How do I know if he accepts it when I repent?
Again, this is what I believe, not a fact, just a belief. I think God reads through our heart, he knows us (the believers), when we repent for something, I think he knows if we are honest or not, if we mean it or not. It's a matter of believing or not. For me it's simple and not mind-boggling AT ALL.
I would like to know what the purpose of believing in god is.
I can only tell you that for me, the conversion to God was life changing. That I'm far from perfect but I want to follow Jesus's principle. Again, I want to. I know for a fact, I'm not always and I don't beat myself over this because I'm only a freaking human.
Believing in God is a part of me, I'm just a regular person and I think the coward who emailed you the threats to hell forgot his own principle from the bible he proclaims to follow. And in between you and I, how in heck would HE know who goes to "hell" or not? You do NOT have to believe in anything.
Does this satisfy you at all (my answers), I wanted to give you a reply and I also wanted to let you know that whether you believe or not (in anything) is totally up to you. I don't think you are wrong for not believing. I made the choices for me, I only know what is good for me and even then, it's not always easy to see. So? Did I pass the test? What do you guys think?
