1) You can't find the answer to your question by analyzing scripture -- if the Bible was clear on this issue (or ANY issue) there wouldn't be so many different views amongst the various denominations.
2) You need to look at this from the perspective of Zen:
Zen can't be taught, it can only be learned. Like Zen, the principles of Christ can't be taught -- they can only be learned. Zen is learned by applying Zen in your daily life. Like Zen, the principles of Christ can only be learned by applying then in your daily life. And I think the principles of Christ are clear from the gospels -- love your neighbor as you love yourself.
3) What is the purpose of your question -- you sound like you think the answer actually has some importance -- but it doesn't:
If the way to heaven is through belief -- then your sincere belief that Jesus is God will lead you to love and worship him which will lead you to want to emulate him which leads you to follow his example of loving your neighbor. If the way to heaven is through works, then you will follow his example of loving your neighbor, and come to love and worship Jesus as the example for your life. Either way, the result will be the same. The Bible and the Gospels are not about what's going to happen to you when you die (how do I make sure I'm going to heaven) -- they are about what you should be doing when you're alive (how do I make sure I'm showing love to my fellow man). Concerning yourself with YOUR afterlife is selfishness, a sin, and you can't sin your way to heaven -- it's the unselfish concern for your fellow man that saves you. It's the doing that counts, not the "being right" about it.
4) You shouldn't concern yourself with doctrine -- that's the problem with ALL religions -- they are concerned with doctrine -- especially the RIGHT doctrine (which separates them from the religions that have the WRONG doctrine) instead of being concerned PRIMARILY with how they treat the rest of humanity.
