Ephesians 4:13

(4:13) Look at the goals of this gifting of the Body of Christ--One, "unity in the faith". We are in union with one another in a single body, the Church, which is joined to Christ as His Bride. Two, "the knowledge of the Son of God." This is an intimate understanding gained through the experience of living "in Him". The result of these is the end product of child training of each believer through to maturity, the "attaining to the whole measure of the fullness of Christ." It is through having our lives taken over step-by-step and by being in-filled by the Holy Spirit that the believer experiences the truths of our standing in peace and union with God. We are one with God. Through maturity we become aware of, and experience, oneness with Him.
