Common Good of the Holy Spirit
1 Corinthians 12:7 (ESV) … “To each is given the manifestation of the Spirit for the common good.”
Paul elaborated on the themes of unity, diversity, and distribution, first stating that God gives a manifestation of the Spirit to each person. The Holy Spirit is the down payment or guarantee of every believer’s future inheritance (Eph. 1:13–14). So all believers receive the Spirit. Paul did not speak only of the Spirit’s indwelling presence here, but of the manifestation of the Spirit. This terminology indicates that every believer has some display of the Holy Spirit’s presence in his or her life.
Also, the manifestation of the Spirit has a particular goal: the common good (cf. 1 Pet. 4:10). The gifts of the Spirit are not principally for the edification of the individuals who receive them, but for the good of all believers
