but all the members of that one body, being many,
are one body, so also is Christ.”
-1 CORINTHIANS 12:12
The Bible says that there is an invisible but very powerful union that exists between Jesus and all His disciples; they are one Body. It is a spiritual union. This spiritual union forms the basis of our relationship and fellowship with Christ.
Jesus says, “I am the True Vine… Abide in Me, and I in you” (John 15:1,4). Jesus compares this union to a vine that has many branches. Each branch lives in union with the vine. The same life flowing in the vine is also flowing in the branches. Jesus says He is the True Vine, and we are His branches. This is spiritual union. As branches, we can only grow and produce spiritual fruit so long as we continue to live, dwell in, abide, and be part of the Vine. So then, union with God is not the reward for spirituality; it is the basis of spirituality.
