Here's an example of what I read this morning:"Christ’s being the firstborn Son of God implies that He has many brothers and that He is the Firstborn among these brothers (Rom. 8:29). The birth that took place through Christ’s resurrection involved the birth not only of an individual but of a group, a group that includes the firstborn Son and the many sons of God. This indicates that through one birth, one delivery, many sons were brought forth. This resurrection was the birth of the corporate child—the corporate new man. Thus, 1 Peter 1:3 says, “Blessed be the God and Father of our Lord Jesus Christ, who according to His great mercy has regenerated us unto a living hope through the resurrection of Jesus Christ from the dead.” God regenerated us through Christ’s resurrection. We, as human beings, were all divinely sonized through His resurrection to be many sons of God to participate in His divine sonship. We are the many brothers of the firstborn Son of God in His resurrection. In resurrection God begot a Son, Jesus Christ, and in resurrection God regenerated many sons. This shows us that the resurrection of Christ was a great delivery. In that same delivery the Firstborn was Christ, and this firstborn Brother had many “twins” to follow Him. In the unique resurrection Christ was born and we were regenerated; hence, we were His “twins” in the same delivery. This was a universal delivery of a corporate child, which included the Son of God as the Head and His many brothers as the Body. The firstborn Son of God is the Head, and His many brothers, sons of God, are the members of Christ. Therefore, Christ’s resurrection was the one universally big delivery of Himself as the firstborn Son and the believers as His many brothers, His millions of “twins.” (The Conclusion of the New Testament, pp. 2941-2943)
