Biblical theology traces an idea, word, or theme in a biblical book, author, genre, testament, or the entire Bible. While the process can be long and involved and requires careful thought, the steps are quite simple.
- Determine the idea, word, or theme to be studied. In this example, I will use the word "heart" (Gk. kardia) in Matthew's Gospel. You can use the search tool at biblestudytools.com. I used it, chose "interlinear" in the sidebar, and clicked "kardia" to fine all the uses of kardia in Matthew.
- Next, read each verse in its paragraph (!!!) and determine what this particular verse says about the idea, word, or theme. Make brief notes.
- Matthew 5:8 can be pure; related to the perception of God
- Matthew 5:28 can sin
- Matthew 6:21 intention revealed in use of treasure
- Matthew 9:4 related to response; ca do evel/good
- Matthew 11:29 can be humble
- Matthew 12:34 source of speech content; evidence of character
- Matthew 12:40 interior
- Matthew 13:15 related to understanding
- Matthew 13:19 can have content stolen by evil one
- Matthew 15:8 can be communal (had by a community); determines intention
- Matthew 15:18-19 source of speech content/behavior
- Matthew 18:35 location of true forgiveness of others
- Matthew 22:37 able to love
- Matthew 24:48 source of decisions/behavior
- Spend time reading over your notes. Look for the structure of the concepts, write the key concepts in bullet form, and cite the appropriate passages.
- moral component, 5:8; 5:28; 9:4; 11:29
- cognitive component, 5:8; 13:15
- volitive component, 6:21; 9:4; 15:8; 15:18-19; 18:35; 22:37; 24:48
- character component, 12:34-35; 15:18-19
- vulnerable to evil, 13:19
- Read through the passages in their groupings and create a full sentence outline of the biblical theology.
- The heart is the location of our moral decision-making (5:8; 5:28; 9:4; 11:29).
- The heart is the gatekeeper and ultimate means of understanding (5:8; 13:15).
- The heart decides our thoughts, motivations, and behaviors (6:21; 9:4; 15:8; 15:18-19; 18:35; 22:37; 24:48).
- The heart is the reservoir of character (12:34-35; 15:18-19).
- The heart is vulnerable to evil attack (13:19).
- You now have a biblical theology of the idea, word, or theme you have studied.
- Now, venture out on your own and trace heart in Mark's Gospel. If you would like, post your results in the comments.
