I don't know what the people who actually voted think, but the closed question doesn't seem to ask about a belief that any particular Christian group actually holds. The open question starts from a particular interpretation of the Bible that seems very natural—likely even.
As far as the site is concerned, questions aren't about what individual Christians believe, but what some Christian group believes. Individuals believe all sorts of things and it would be an impossible task to tackle questions about all the possible things that Christians might assert. We are mostly interested in coherent systems of theology, so it's hard to know how to take a question that asserts that thinking a lot about God is somehow correlated to getting in heaven. It just doesn't make any theological sense (even if it might make common sense).
It's even likely that taking on all systems of Christian theology might be too much. There are groups that think Jesus wore pants, was buried in Japan or did not even exist. With such large variations in belief systems, it can be hard to make any sense out of answers unless the scope of the question is reduced to particular groups of Christians.
As always, don't forget that questions may always be opened if they are edited into a state where people are will to vote to reopen. In this case, if you want to pursue the closed question further, I suggest doing some research to find out which (if any) system of theology has something meaningful to say about the question and scope it narrowly.
