So no need to keep going to Church after all then, cool.
Because how will these Jewish and Muslim apostates come to an understanding of God if the religion they persist with, happens to be the wrong one? Their Rabbis and Imams aren't going to tell them "Oh, perhaps this is the wrong religion and some other religion is the one true religion...", or do you think that multiple and mutually exclusive religions can be the "one true religion" at the same time? You're not making any sense...
If the models are incorrect, then they get discarded if they serve no purpose in the mean time. That's how Science works, and it has worked like this since the dawn of the scientific method. That's no reason to give up Science though, because Science is a method to sort fact from fiction, it's what gives us all the modern conveniences you enjoy, all the food you eat and all the longevity and health that goes with it. To give up science because a model isn't right shows your ignorance about what science is - you might as well be saying you'll just give up on civilisation and humanity at the first friend you lose.
Same with religion, if you can no longer believe the religion you're in, then staying there in an effort to self-deceive isn't the way forward. Try another religion, or no religion at all for what its worth, and seek others until the right religion delivers conviction of belief to you.
