Why Adhere to the Bible? - (Part 1) Because it's God's Word

Because the Bible is the inspired word of God (2 Tim 3:16), it provides us with something that we can not get anywhere else, it gives us God's perspective on things.
This world contains a wealth of information, and our library's are stuffed full of books on science and theology and stuff, but only God can speak to us with absolute certainty about eternity and the future. Though much can be learned of God through nature, we need to go to the Bible daily, and study it long and hard in order to gain this knowledge, but we should never just skim it and kind of “read” it in our spare time. We need to devote the greater part of our memory and time to the studying and application of the the only divinely inspired word, and ask for God's direction in those pursuits.
The Bible also tells us about God, and of His characteristics, and His feelings toward a certain action. Without that knowledge that is stored in the Bible, we are blind to all He has said and done for us.

Most people will say that because the Bible was put to paper by finite humans that it can not be excellent enough to be the word of God. Or because the Bible was written way back in the “Bible times” and they didn't know that much back then, it couldn't be applicable to us today. Some people will bring up the example of Luke 10:4: “Carry no moneybag, no knapsack, no sandals, and greet no one on the road.” Does this mean that missionary's are supposed to go barefoot? Is it still valid in a shoe-wearing world? How literally should we take this passage? Those are very good questions, and people run into questions like them all the time. Now you probably don't think that we should all go barefoot, but let's look at the following questions: Is this verse entirely custom, entirely principle, partly principle-partly custom, or partly principle? Whenever you are looking for the answer, it is important to always take an exegetical approach, and ask God for the wisdom to understand His scriptures.

There's a reason why the Bible is the worlds best seller. Adhere to that book and the Writer of that book!
