You should take action to live a meaningful life, that is your responsibility (that is salvation for me) Religions may have different points of view, but that does not mean they are false, they just provide different answers to different needs. It is like political parties, not because they disagree means that they are false. They just pursue different interests.
Religion has emerged independently through history in many cultures, and that is because humans have the natural need to believe in something and organize themselves to live in a community. Religion provides an answer for that. It also provides a guideline so you live a meaningful life and achieve the highest human development possible.
My religion states that killing, raping, stealing, harming, lying are bad behaviors. I do not care if it is Allah, Jesus or Mary, or if there were 5 or 12 apostles, what is important is that you have a good relation with your surroundings, with your family, friends, and community. The religion that allows you to do that is the right one for you. Take into account that people have different needs, and thus, different solutions (religions) are needed, it is your duty to research which path to follow. On that path you may encounter other people who share your beliefs and hopefully those will be the same religion. There are a lot of congregations inside a religion, so surely there will be a place were there are people like you.
You are not alone if you think that it is outdated to believe that an old man in the clouds is watching you and will strike you with a lightning if you misbehave. People may be wrong about teaching religion and even in preaching it. There are a lot of bad things in people who preach. But it is duty of every member of a society to fix what is wrong. Religion as an institution is good when you know how to use it, just like political parties in a democracy.
