Sorry I did not go through the responses. But here is my input.

1. We are not in a good position to tell the differences and similarities. However, what I know is that the most difference is about the way each religion look at Jesus.

2. Nothing wrong in being a good Christian or a good Muslim. Each follow his holly book which is sacred.

3. We usually do not select our religion. We inherit from our parents. Few decide later to convert for some reason.

Finally, one important thing to highlight is that many Churches consider Muslims as non-believers. Think this comment will trigger a new debate. You might not know about this fact in the west. Few know about it in our area.

Peace
