The Bible was written not to satisfy your curiosity but to help you conform to Christ's image.
If you cannot be accused of exclusivity, you are not discipling.
The Bible is the divine means of developing spiritual maturity. There is no other way.
God is not looking for more stars; He's looking for more servants.
Bible study is essential to spiritual maturity.
Maybe you've attended church for five, ten, or even twenty years, but you've never cracked open the Bible to prepare yourself for effectiveness as His instrument. You've been under the Word, but not in it for yourself.
