There is no doubt that it is essential for Christians to have a thorough knowledge of Scripture. Of all the things worthy to be memorized, the Bible should be at the top of the list. But, a great mistake occurs when the Bible is read and treated like a textbook. Christians have a much greater responsibility— a responsibility deeper than merely obtaining knowledge.
There are many beings who have a great breadth of knowledge. Satan knows and understands the truths found in Scripture. In Matthew 4, when Jesus was tempted the second time, Satan knew the Bible well enough to provide Jesus with twisted Scriptural support. The demons themselves believe God is one, and they tremble (James 2:19). Scripture also makes it clear that all men know of the one true God (Romans 1:18-20). Merely believing and knowing is simply not enough!
At the center of all Bible reading is the condition of the heart. If the truths being read do not affect the heart, something is terribly wrong. When reading of Christ's agonies on the cross awakens no response or worship, Scripture reading becomes nothing more than a legalistic pastime. The pursuit of knowledge is only a worthy endeavor when the end goal is adoration and glorification of God.
