The Scofield Bible Commentary, by Cyrus Ingerson Scofield, [1917], at sacred-texts.com
gave
In (Co1 12:8-28), the Spirit is seen as enduing the members of the body of Christ with spiritual gifts, or enablements for a varied service; here, certain Spirit-endued men, namely, apostles, prophets, evangelists, pastors, and teachers, are themselves the gifts whom the glorified Christ bestows upon His body the church. In Corinthians, the gifts are spiritual enablements for specific service; in Ephesians, the gifts are men who have such enablements.
some
The Lord, in bestowing the gifted men, determines, providentially, (for example); (Act 11:22-26), or directly through the Spirit, (for example); (Act 13:1); (Act 13:2); (Rev 16:6); (Rev 16:7) the places of their service. "Some" (churches or places) ,need one gift, as, (for example); evangelist; "some" (churches or places) need rather a pastor or teacher. Absolutely nothing in Christ's service is left to mere human judgment or self-choosing. Even an apostle was not permitted to choose his place of service. (Act 16:7); (Act 16:8).
