This article offers a theological discussion on the relationship that must be understood in the church between law and grace. In particular, the author seeks to find the proper place of the law of God in the life of the believer. The discussion, therefore, includes an exploration of such phrases as "under law," "under grace," the Mosaic covenant, and holiness.

In what way is there continuity between the Mosaic covenant and the new covenant? Covenant theology is known for its emphasis on the unity and continuity between the testaments. Karlberg surveys the development of federal theology. He tries to understand the strong and sometimes even aggressive debate surrounding these issues.

One of the classic themes of theology is the matter of law and grace. This article considers the relationship between the law of Moses and the grace and truth that came by Jesus. Is the law still mandatory? Leviticus 18:5 and Deuteronomy 30:16 are compared with Romans 10:4.

This article is about justification by faith alone and through grace alone. The author also discusses the relation of faith and merit, law and grace, law and gospel, and justification and sanctification.
