I am a person who is dedicated to the study of both biblical and systematic theology. Though there are quibbles regarding the exact definition of these categories, I will simply categorize the former as the historical and thematic study of the Scriptures as it is revealed progressively in redemptive history, whereas the latter is dedicated to the orderly arrangement of what the Bible says about various topics or doctrines (e.g. God, Christ, Spirit, church, salvation, end times). For an excellent article on the history and differences between these two disciplines see works by D. A. Carson or Andreas Kostenberger.
In a later post I hope to elaborate on these points, but I just wanted to post some videos here of a biblical theologian who always stirs my thoughts and affections for the Lord, Jim Hamilton. Below are two videos to watch, one an academic lecture, the other a recent sermon. Both, in my estimation, are examples of biblical theology that yield implication relevant to systematic theology. Watch and enjoy, and be stirred to take up the Scriptures and to know your God.
