World Lenses

I've often wondered about how unsaved people view the world. And by that I mean what sort of lens do they see? A moral one? A "Do what you want" type of lens? I'm beginning to realize there are only two ways to view the world: Christian, or non-Christian.
I know that seems really simple, so let me put it this way.
When it is completely dark around you, you don't know what sort of dangers are near you, or what your surroundings are. You have the basic knowledge of what is up, down, left or right, but you have no clue what direction is north, south, east or west. You can have all of your opinions about which way is north, but there is no certainty, or any way you can prove that the way you are looking is in fact north. To me, this is why the world believes in relative truth. In the mind of the world, if we are all in the dark, truth (Or to continue the example, direction) can be anything you want. Eventually some of the those relative truths will get close, but it will never be the absolute truth.
When you accept Jesus into your life, the bible tells us we are then filled with the Holy Spirit. And our mind becomes free and we began to see the world in the light rather than in the darkness. Now that we can see everything in the light, we begin to see all of the dangers, traps, cliffs and other things harmful to us. Because we see, we avoid these things, but those in the dark blindly stumble into those traps because they don't know any better.
Now, to continue the use of directions as an example. Since we as Christians are in the light, we can see our compass clearly and thus we understand north is north because our compass says so and not just because we feel a certain way or we say so. In a Christian's life, their compass should be the bible, has to be the bible. Now that we can see that murder is a sin and bad, not just because we feel that way and think it's bad, but because the Bible says so.
As a Christian myself, I have noticed when someone is going to attack Christianity or a certain thing Christians believe, they most often go after the Bible first. This is because if a man in the dark, and a man in the light are debating about which way is north, the man in the dark will obviously try to say that the man's compass is off kilter, that it is pointing in the wrong direction. Once the man in the light is without his compass, he loses any sort of advantage he has and is then trying to use logic and reasoning to find out which way is north, which is infinitely harder than using a compass.
There are those as well, who try to pick and choose from the Bible. To them I say, do you pick and choose from a compass? If you agree north is north, and south south, all is fine and well, but if you think that east is west and west east, you will be all twisted up and not able to go the direction you intend and you will end up lost.
It is either all of the Bible, or none of it. There is no in between. And hopefully now you see it is good to study the Bible, because a Christian without their Bible is like a hiker without a compass. You can stay on the path for so long, but when a fork in the road comes, how will you know which way to choose?
