A.T. Robertson Commentary 1 Corinthians 12:9

"to another faith, in the same Spirit; and to another gifts of healings, in the one Spirit;" — 1 Corinthians 12:9 (ASV)

Faith (πιστις). Not faith of surrender, saving faith, but wonder-working faith like that in 13:2 (Matthew 17:20; Matthew 21:21). Note here εν τω αυτω πνευματ (in the same Spirit) in contrast with δια and κατα in verse 8.

Gifts of healings (χαρισματα ιαματων). Ιαμα, old word from ιαομα, common in LXX, in N.T. only in this chapter. It means acts of healing as in Ac 4:30 (cf. James 5:14) and Lu 7:21 (of Jesus). Note εν here as just before.
