In his book, "Not In God's Name", Rabbi Jonathan Sacks argues that religions (almost all religions) need to change their focus. Instead of focusing on converting as many people as possible to think and believe like they do, religion should rather shift their focus to finding ways to make this world a better place.
"Our most deeply held beliefs are not fundamentally intellectual. They are emotional, and they are social. That goes for religious beliefs and it goes for political leanings as well. In fact, the same thing can be said for just about any other bedrock belief structure we can have."
