For the first paragraph, I would be curious to find out. But it's hard for me to imagine alternatives, and how I would react to them. If there was no God and everything just happened by chance, I would say that seeing how much suffering there is in the world, and how helpful an act of love is despite it all, I would consider acts of love to be a high goal worth spending one's life to attain. With out a God, I don't know what makes a person good. I don't think being good is limited to those who believe in God, and I think it's a thing that goes beyond the acts. As for the foundation of my life, again, I find it hard to imagine what other foundations there are, and how I would react to them. If I were an atheist, and I were an honest philosophical one who believed that we must overcome evil with good, it still wouldn't change anything. But that is the thing - I don't know if I would be a good enough person to be the type of atheist I described. What I say now, I say as a person who has been influenced by my belief in God.
I do have the courage to look at other religions and think that maybe Christianity is no different. Perhaps that is why I am a so called "liberal Christian". The problem is that I am caught up with two fashionable ideas with liberal Christians: 1) People who follow what Jesus said without ever having heard of Him or knowing him could be just as much "saved" (see the parable of the separation of the sheep and goats) 2) Many myths and religions seem to reflect some of the same ideas in Christianity and Judaism: the idea of a God who becomes incarnated as a human and then dies or is killed and then comes back to life.
I think that when I reject a religion or a system of beliefs I tend to do it based on things like morally allowing for things like the murder of people, or a moral code that is based appearances and not on inner morality.
I think it is right to just be kind, honest and good just for its own sake. I have given up doing things for a reward in heaven, mostly because I know how poor I am there anyway. Also because I don't know how wonderful the reward will be, and because motivating myself with rewards never seemed to motivate me enough (and would tarnish the kindness anyway,) I'd rather consider it a reward if I do get to one of those rare instances of real kindness. Actually there is always a certain joy when you do the right thing for the right reasons.
Firstly, I am not such a good person. I believe that my best friend from Israel who is not a Christian is more good than me. She has out of her natural motivation and interest worked in orphanages, and in teaching and helping new immigrants. She is studying to be a therapist and has this natural sensitivity to people and their needs. She was the courageous girl to tell all her friends that she believed Arabs were human beings like she is one. (A truism that some people over there forget)
So any way, I am not such a good person, I need help, I need something beyond what I can give myself. I am a lazy selfish person, which hinders me form being kind and doing acts of love.
But more importantly, here is where my understanding diverges from yours:
I read a book about people who died for a few moments or hours and then came back to life. The book gave examples of people from many religions as well as atheists going to an after life. When these people die, they go through stages, and the amount they die gets them to different stages. Those who die enough meet Christ. (Some go to some sort of hell, but get out of it when they call on Jesus he intervenes). Others only go through what is known as the tunnel experience, or someother stage. According to the testimonies, Christ is this being of light, that does nothing but love you and accept you. He never judges you. It is you who judge yourself because you wish you were as good and as loving as Christ. You said reward? The reward is having done a good deed, good from your heart good for no other reason than goodness. This seems to bring incredible joy to Christ. When you hear testimony after testimony like this, you no longer want to be a victim of superstitions, do's and don'ts, of hell and heaven sermons, of calculating rewards or anything like that. You just feel that this is the person you want to know, be like, and learn from. If you love being good and kind for goodness's sake, you've found a friend who agrees with you, and approves of the way you see things. Reading these testimonies has only re-enforced in me the belief that God is there and that Jesus is there, it has given me great joy see what this life and the next are really all about, and to see how it all falls in line. Even if I am wrong about all this, I still can't see how I would regret anything. You want to be good for it's own sake. I need help to be good for it's own sake and believe I have found a friend who will help me find the way and the maturity to be good. So neither of us will have anything to regret, either way, God or no God.
