What Does being One with Christ Look Like?
by John Robertson
Jesus prayed that the disciples would be one with he and the Father at John 17:17-23. What does this mean and what does it look like in the lives of the disciples? A great help with this is found in the book of 2 Samuel chapter 5. King Saul was killed in battle along with his son Jonathan. The men of Israel come to David to anoint him the next king of Israel. The men proclaim, “Behold, we are your bone and your flesh” (2 Samuel 5:1).
There is a great lesson to learn if we keep our foundational principle of shadows and types in their proper place. David, as the anointed king of Israel, is a type of Christ (1 Samuel 16:12-13 and Psalms 22). Israel is a type of New Testament saints or Christians (Romans 9, 11). The shadowy teaching is that if the saints are the body of Christ (Ephesians 1:22-23 and Romans 16:16), then it stands that they are “bone of your flesh” (they are one and the same person) (1 Corinthians 12:12-14, 25-27).
There is a similar statement at Genesis 2:23 where Adam refers to Eve his wife saying, “23 This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man.” The marital relationship between Adam and Eve is a shadow of the relationship between Christ and his church (see Ephesians 5:22-33). If the church is the body of Christ, then they are bone of his flesh.
Each saint is a “member,” or a body part, of Christ (Romans 12:5). This helps us with our terminology or language. To say that one is a ‘member of the body of Christ’ is to say that they are one with Christ’s body the church. Each saint is a body part of Christ’s body the church. The saint, along with other saints, comprise the ‘sum total’ (πληρωμα - LS 647) of Christ (Ephesians 1:22-23; 3:16-19; 4:12-13). Sometimes people say they want to “place membership with a local body of Christ.” Such language is somewhat foreign to the principle of what Christ’s body is. The saints are body parts or members of Christ.
Consider the prayer of Jesus that the disciples be one with him and the Father (John 17:17-23). To be a member, or body part of Christ, is to be holy as he is holy (see “glory” given at John 17:22-23 and Romans 3:22-24). The apostles commanded this oneness (1 Corinthians 1:10 and Romans 15:4). When one is baptized into Christ, for the forgiveness of their sins, they are added to the Lord’s body as a body part (Acts 2:38 and 5:14). They are in the same or one place of Christ, his house, church, or body (Isaiah 57:15; 1 Timothy 3:15). This makes them one from the perspective of having a common life of holiness. Fellowship occurs in this holy state between God and his saints (1 John 1:3-7). So, the gospel calls people into this oneness of holiness with Jesus through the forgiveness of sins (John 6:44-45; Hebrews 11:6). It is the high and holy calling of Philippians 3:14.
