In applying covenant theology, we need to recognize that God covenants corporately and not simply individually. God’s covenant with Abraham was not just to Abraham but “to [his] offspring” (Genesis 15:18. 17:7). This does not remove the individual, but the individual does not simply remain an individual. Every individual is born naturally into a family and a people. Likewise, an individual believer is born supernaturally from above into a fellowship with Christ as Head. The individual Christian is part of a family; the “household of God” (Galatians 6:10, Ephesians 2:19, 1 Timothy 3:15, Hebrews 3:6, 10:21). Thus the application of the covenant primarily happens in the household of God, that is, in the church. It certainly has implications for the individual and for the natural family, but is seen primarily in the church. This means that a faith expressed solely as “just God and me” is foreign to the pages of scripture.
