Systematic theology will ask questions like "What are the attributes of God? What is sin? What does the cross achieve?" Biblical theology tends to ask questions such as "What is the theology of the prophecy of Isaiah? What do we learn from John's Gospel? How does the theme of the temple work itself out across the entire Bible?" Both approaches are legitimate; both are important. They are mutually complementary.
D. A. CarsonJesus is hungry but feeds others; He grows weary but offers others rest; He is the King Messiah but pays tribute; He is called the devil but casts out demons; He dies the death of a sinner but comes to save His people from their sins; He is sold for thirty pieces of silver but gives His life a ransom for many; He will not turn stones to bread for Himself but gives His own body as bread for people.
D. A. CarsonThe truth of the matter is that all we have to do is live long enough and we will suffer.
D. A. CarsonSome Christians want enough of Christ to be identified with him but not enough to be seriously inconvenienced.
