Like you, I volunteer using my skills with the disabled (teaching them to sail). Some are amputees returning from Afghanistan - I'm ex-military. One of the most rewarding areas of my life.<quoted text>
I paid 3 families rent and once a month I give out food at the mission to families in need. At Christmas I hand out gifts to kids my kids only get one gift from my wife and I so we can help poor kids. I've done this the last 3 years. What do you do to help your fellow man? Point an laugh and thank the whatever you believe in its not you?
As for religions that don't believe in satan or the Christian God I have no idea. However missionaries do some great work. I also don't think God punishes those who don't know of him. The Bible says where there is no law their is no sin. For those how have the chance to know and ignore him they're in trouble.
Have you ever thought of the ramifications if their religion, not yours is the "right" one?
