Good post. I think this question really gets some good thought flow. I personally believe in God. For one reason, because i've seen too many things happen in life that i just cant say was luck, or chance. Although i realize, the human mind seems to always question things like what crazydrinker said. Was it divine intervention, or was the gas guage sticking on his truck?
I was on my way home last winter from a job with my brother, and we had 8 hours to travel to get home. It was about 25 degrees that day, and the wind chill was colder than that. We were about 2 hours into the trip when his truck broke down. We were on a main highway, but miles from any town. Of course after twenty minutes, we ran out of heat, and i discovered the idler/tension pulley was completely broke off. We didnt have tools, and didnt know anyone in the area. I told my brother i wanted to say a prayer, at wich he agreed it couldnt hurt. (we were both raised JW's, but now i attend a local church, and he was never baptized, and had quit going for years) So i said a short prayer, left the matter in Gods hands, and covered up with a blanket. Within twenty minutes or so, a truck of the same make and model, pulled up in front of us. An elderly man walked up and asked what was wrong. I explained to him the problem, and he said he would be glad to help us, as he had fixed the same problem on his truck before, and had all his tools with him. He gave us a ride into the nearest town, we bought the part, and he fixed the problem.
I realize, it takes faith to believe this was an act of God. I couldve rationalized that it would have happened whether i had prayed or not. And maybe it would have. But i have lived on both sides of life. With God in my life, and without God in my life. And there is no way i ever want to go back to the former way of things, without him. No, im not saying that everything is peaches and cream now. I still have to wrangle with this flesh of mine and all the regular problems of life. But a GIANT weight has been lifted off of my shoulders, now that i realize i can do nothing of my self to earn salvation, and that i will never please him by some good act, or living a certain way. All i have to do is have faith in him, knowing that as Romans 8:28 says "ALL THINGS work together for GOOD to them that love God".....
I think many people see religion as just a way of "cleaning up" your life, and its no wonder. Look at the JW's, and countless of other religions that teach salvation is earned by how you live, how much good work, ect..... These things by themselves are fine and good, but dont produce saving faith. Instead, they really produce the opposite. Faith in yourself and what you do. And from what i see in scripture, its what Gods son did that matters. Everything we need to be in front of a Holy God was accomplished by his dear Son.
If i didnt believe in God, then what would i have to look forward too? Maybe a few short years on this planet filled with all kinds of problems, but NO HOPE for the future. Just like when Jesus asked the twelve apostles, will you go away also? Peter said, "Lord, to whom shall we go? you have the words of eternal life." (Jn 6:68)
