What if it's all untrue?

I'm not gonna lie...i've thought about this question a lot in my life. What if God, my faith, everything i believe in, what if it's all untrue. what if we get to the end of our lives and we realize that it's not what we thought? what if some other religion turns out to be "the right one"? What if? We could every monet for the rest of our lives thinking about these questions and never get anywhere. i have amore prominet question for you...are you gonna let the "what if" rule your life? are you gonna let them determine the course of your life? these questions matter little to me in the grand scheme of things. Yes i believe that my god is "the right God" ( i like calling him my God, it sounds much more personal than just God) and yes i believe that the bible is realy and that everything that is printed in there is the truth. I live my life by faith, but also by love and by relationship. I try to please God and love others as he has told me to do so if i get to the end of my days and it turns out that some other religion is right...well that really sucks. but i know that i've spent my life helping others and serving a purpose higher than myself. And that is what God has called us to do. There's a Nicole Nordeman song that i really like that fits perfectly with this topic.

What if you pick apart the logic and begin to poke the howl what if the crown of thorns was no more than folklore that must be told and retold.
But what if you're wrong, what if theres more
What if theres hope you've never dreamed of hoping for?
What if you jump, just close your eyes? What if the arms that catch you, catch you by surprise?
What if he's more than eneough, what if it's love?
