There are 3 main goals of Bible study, according to Scripture.
The first goal is stated in II Peter 1:20-21."But know this first of all, that no prophecy of scripture is a matter of one's own interptetation, for no prophecy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God." This means that the first goal should be to discern the intended meaning put forth by the inspired writers in the original language, using principles of proper interptetation.
II Timothy 2:15 presents the second goal."Be diligent to present yourself approved to God as a workman who does not need to be ashamed, handling accurately the word of truth." We are to accurately know the truth of the Bible, through diligent study.
The third goal is mentioned in II Timothy 3:16-17, which says "All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness, that the man of God may be adequate, equipped for every good work." This means spiritual maturity combined with good works should be the end result.
