1 Corinthians 12:7

'But to each one is given the manifestation of the Spirit to profit withal.'

From considering the mighty power of the triune God in His working on behalf of His people, Paul now comes down to the individual believer. The mightiest Being imaginable resources every believer as He chooses. Thus there is no room for jealousy or boasting. Each one is in some way given the manifestation of the Spirit that all may profit. This may mean that each one who is given a manifestation of the Spirit is given it for the benefit of the whole church. Or it may signify that each member of the church can be sure that they will have some gift from God through His Spirit with which they can serve in the church and make the truth known in one way or another, so that all may profit. Both are in fact true, especially if we take the gifts in their wider sense as revealed elsewhere. And all are necessary to the wellbeing of Christ's body (Ephesians 4:15). None can do without the other.

'Is given.' The passive verb regularly indicates that the source is God. Thus the source of the Spirit's genuine gifts is God, and the manifestation of the Spirit at work is God's gift to His own.
