Why do you read the Bible? to what end?

this text is from the 1st chapter in J I Packer's "Knowing God":

For this very reason we need, before we start to ascend our mountain, to stop and ask ourselves a very fundamental question—a question, indeed, that we always ought to put to ourselves whenever we embark on any line of study in God's holy book. The question concerns our own motives and intentions as students. We need to ask ourselves: What is my ultimate aim and object in occupying my mind with these things? What do I intend to do with my knowledge about God, once I have it? For the fact that we have to face is this: If we pursue theological knowledge for its own sake, it is bound to go bad on us. It will make us proud and conceited. The very greatness of the subject matter will intoxicate us, and we shall come to think of ourselves as a cut above other Christians because of our interest in it and grasp of it; and we shall look down on those whose theological ideas seem to us crude and inadequate and dismiss them as very poor specimens. For, as Paul told the conceited Corinthians, "Knowledge puffs up.... The man who thinks he knows something does not yet know as he ought to know" (1 Cor 8:1-2).

To be preoccupied with getting theological knowledge as an end in itself, to approach Bible study with no higher a motive than a desire to know all the answers, is the direct route to a state of self-satisfied self-deception. We need to guard our hearts against such an attitude, and pray to be kept from it. As we saw earlier, there can be no spiritual health without doctrinal knowledge; but it is equally true that there can be no spiritual health with it, if it is sought for the wrong purpose and valued by the wrong standard. In this way, doctrinal study really can become a danger to spiritual life, and we today, no less than the Corinthians of old, need to be on our guard here.

But, says someone, is it not a fact that a love for God's revealed truth, and a desire to know as much of it as one can, are natural to every person who has been born again? Look at Psalm 119: "teach me your decrees"; "open my eyes that I may see wonderful things in your law"; "Oh, how I love your law!;" "How sweet are your words to my taste, sweeter than honey to my mouth!"; "give me discernment that I may understand your statutes" (vv. 12, 18, 97, 103, 125). Do not all children of God long, with the psalmist, to know just as much about our heavenly Father as we can learn? Is not, indeed, the fact that we have received a love for his truth in this way one proof that we have been born again? (See 2 Thess 2:10.) And is it not right that we should seek to satisfy this God-given desire to the full?

Yes, of course it is. But if you look back to Psalm 119 again, you will see that the psalmist's concern to get knowledge about God was not a theoretical but a practical concern. His supreme desire was to know and enjoy God himself, and he valued knowledge about God simply as a means to this end. He wanted to understand God's truth in order that his heart might respond to it and his life be conformed to it. Observe the emphasis of the opening verses: "Blessed are they whose ways are blameless, who walk according to the law of the Lord. Blessed are they who keep his statutes and seek him with all their heart.... Oh, that my ways were steadfast in obeying your decrees!" (vv. 1-2, 5).

The psalmist was interested in truth and orthodoxy, in biblical teaching and theology, not as ends in themselves, but as means to the further ends of life and godliness. His ultimate concern was with the knowledge and service of the great God whose truth he sought to understand.

And this must be our attitude too. Our aim in studying the Godhead must be to know God himself better. Our concern must be to enlarge our acquaintance, not simply with the doctrine of God's attributes, but with the living God whose attributes they are. As he is the subject of our study, and our helper in it, so he must himself be the end of it. We must seek, in studying God, to be led to God. It was for this purpose that revelation was given, and it is to this use that we must put it.
