So, like only the Jehovah's Witness' think they are going to heaven kinda thing?
Sorta... Like the thought that only those that are "going to heaven" are believers in the gospel of Jesus Christ.
Many months ago I started asking questions about this... I assumed that if our eternal well-being is based on belief than a loving God would put us on level playing field when it comes to the ability to believe in Him or not. My conclusion was that we're not all given an equal opportunity... Some more than others and some not at all. For a loving God to not level the playing field per say with something as important as our eternal destiny doesn't sound just to me.
This idea led to many, many more questions and believe it or not... The bible had the answers but I had to approach it with a clean mind, not muddied by the philosophies of fundamental Christianity that I was raised with.
