The last part of this verse is much shorter in the Greek, as the words in italics in the KJV indicate. Translated literally, it reads, “but also we shall be of the resurrection.” Some have applied this passage primarily to the future resurrection, but this is not indicated by the context. Paul is emphasizing that as the believer shares in the likeness of Christ’s death by himself dying to sin, so he must share in the likeness of Christ’s resurrection by rising to a new life of righteousness. In both these experiences he is showing his vital union with the Saviour.
It is true, of course, that spiritual rebirth and life in the Spirit lead to final resurrection and eternal life. In fact, for those who walk in newness of life, eternal life has in a sense actually begun (see on John 8:51).
Planted together.
Gr. sumphutoi, “grown together.”“Planted together” is not a precise rendering of the Greek word. The idea is to be vitally connected. It is a picture of the vital union that exists between Christ and those who have entered into the intimate fellowship of faith with Him. Compare Christ’s parable of the Vine and the Branches (John 15:1-8). Unless the believer first enters by faith into this vital connection with Christ, it is impossible for him to walk in newness of life, no matter how much he may desire to do so.
