It's not as if the New Testament writers came along and said, "The culmination of Old Testament books is more books, New Testament books." In some ways they thought instead of the culmination of Old Testament books being Christ himself, the word incarnate as the opening verses of Hebrews 1 put it. In the past God spoke to the fathers by the prophets, but in these last days he has spoken to us by his son and the son is revelation.
D. A. CarsonThe Christian's whole desire, at its best and highest, is that Jesus Christ be praised. It is always a wretched bastardization of our goals when we want to win glory for ourselves instead of for him.
D. A. CarsonSome Christians want enough of Christ to be identified with him but not enough to be seriously inconvenienced; they genuinely cling to basic Christian orthodoxy but do not want to engage in serious Bible study; they value moral probity, especially of the public sort, but do not engage in war against inner corruptions; they fret over the quality of the preacher's sermon but do not worry much over the quality of their own prayer life. Such Christians are content with mediocrity.
D. A. Carson"Biblical theology" refers to something more precise than theology that is faithful to the Bible. It might be helpful to draw a contrast: at the risk of oversimplification, systematic theology tends to organize theology topically and with an eye cast on its contemporary relevance, while biblical theology tends to organize the same biblical material so that it is easier to see the distinctive contribution of each biblical book and human author, and to trace the trajectories of themes across the Bible so we see how the books of the Bible hold together.
