There are two types of revelation, general and special. All learners can know general revelation because it has been revealed in the natural world. General revelation, therefore, is primarily sensory and discovered through sciences. Only some can know special revelation though. It is revealed by God through his Holy Spirit. The Christian learner should study both as he is able to know both.
Going back to the question of "What is Truth?" we learned recognized two kinds of truth: (a) natural; and (b) supernatural. Natural truth is observable by the human eye (or the aided human eye in the case of microscopic things). Supernatural truth, on the other hand, is recognized by experience and special divine revelation. For example, natural revelations are those things we can come to know through the use of empirical science as to where supernatural (special) revelations are those which God reveals to us.
Scripture, being the very words of God, explain how God created everything originally good. Thus, it is also good (valuable) for us to study the natural world as well as theology and philosophy. By studying these things we can come to greater knowledge of God. At the same time, not all science, theology, and philosophy is true. Thus, we use the Word of God (the 66 books of the Bible) to discern what is truth. If it is true it will not run contrary to the Word of God.
If something does run contrary to God's Word, then there are three possibilities: (a) we have incorrect truth claims; (b) we have interpreted Scripture wrongly; or (c) we have incorrect truth claims and we have interpreted Scripture wrongly.
