so by this route of thinking, as well as that of some others here...y'all make it sound like heaven is some kind of "exclusive club"....and Jesus, as you people see him is the "ticket"...
that may be how you see following Jesus' teachings turn out...but I disagree...
it IS up to God to choose where we go when we pass from this world...each and everyone of us have a chance to advance our spiritual beings to a higher plane...(heaven to some)...and it all depends on what we need to "learn" as to how far we advance each time. Following the teachings of Jesus, because He is teaching the Universal Law of God is how we do it...but it is God that knows and only God that makes the choice of whether we go to "heaven"...not another human that questions whether we are "Christian" or not...
reguarding the origional question...it is Gods choice what happens to us when we pass...we that are still living should concern ourselves with where we might eventually end up and learn our lessons well...
