It all comes down to whether or not how much you believe you are in control of your life, or whether you believe external influences will override your own actions which will be causal to the outcome.
I mean, it is possible to believe in God, ask for guidance, forgiveness (this includes in a social setting with other people to, i.e. forgiveness for maybe cheating on someone, or guidance on what approach to take within a job interview -just examples), its down to the individual to make things happen as external factors can only do so much to affect the choices you make as an individual.
even as a group where peer pressure may arise, or a norm, the individual has the right to execute their choices and stand up for what they believe in otherwise just blend into the background.
So religion can be used as guidance (bear in mind, some may need or want this support i.e. the religious) and some may want to go solo with it, or find their own way - similar to what someone posted earlier. inclusion within a [enter religion] community helps make you be a part of something and gives you a sense of belonging and a role/responsibility to that group, just as anyone would be for example in self-help group. depends which route you take, down to the individ - their choice.
