What If or Sarah Laughed

So, what if all the people around the world dying or killing in God’s name are dying in vain. What if all the people praying for a world to come, end up with silence and nothing more? What if we followed all the laws; lived with sets of ethos and beliefs that were unbreakable, did not steal or kill because we did not want to do unto others what we did not want we lived by; would the faith in a higher power and a world to follow; all be a waste of time?
