"Which of the religions of the world gives to its followers the greatest happiness? While it lasts, the religion of worshiping oneself is the best. ... From the moral point of view it is very difficult! I didn't go to religion to make me happy. I always knew a bottle of Port would do that. If you want a religion to make you feel really comfortable, I certainly don't recommend Christianity. I am certain there must be a patent American article on the market which will suit you far better, but I can't give any advice on it." -C. S. Lewis, "Answers to Questions on Christianity"

If you're looking for religion to make you happy, Christianity isn't the one for you. If you're looking for a religion that makes you better, that answers big questions, Christianity is a pretty good option.
