Please do not assume that everyone believes in your belief. Such a statement like "there is no doubt that we all believe in God" may actually be offensive for some.
Also, please do not impose your beliefs to others forcefully. It's okay to share your thoughts, but to resent someone because they don't believe in the things you do may raise quite a lot of eyebrows, or at least some facepalms because of some of the stupidity you spurt out in the process of doing so.
