What is it?

Biblical theology is sound doctrine; it is right thoughts about God; it is belief that accords with Scripture.

Where is it in the Bible?

1. The entire Bible teaches sound doctrine.
2. Many New Testament books, such as Paul?s epistles to the Romans and Ephesians, are stuffed to the brim with rich doctrinal teaching (see Rom. 1-11 and Eph. 1-3).
3. The authors of the New Testament frequently argue that sound doctrine is essential for healthy Christians and healthy churches (see 1 Tim. 1:5, 2 John 1-6, and Titus 2:1-10).

Why is it important?

Biblical theology is essential for

  • Evangelism. The gospel is doctrine. Therefore, sound doctrine is necessary for evangelism.
  • Discipleship. Jesus prayed, ?Sanctify them in the truth. Your word is truth? (Jn. 17:17). Christians grow by learning and living in light of the truth?in other words, by sound doctrine.
  • Unity. According to the New Testament, the only true unity is unity in the truth (1 Jn. 1:1-4; 2 Jn. 10-11).
  • Worship. To worship God is to declare his excellencies (1 Pet. 2:9-10) and to exalt him because of who he is (Ps. 29:2). True worship is a response to sound doctrine.
