1 Corinthians 14:12
12 So also you, since you are zealous of 1aspirits, seek that you may 2excel for the 3bbuilding up of the church.
121 Here the apostle said, "So also you, since you are zealous of spirits." This shows that in their spiritual pursuings in those days, because of their background the Corinthian believers, who were Gentiles by birth, confused the unique Holy Spirit with the various evil spirits; they were not clear about nor did they adequately hold the uniqueness of the Holy Spirit. This is proved by the words but the same Spirit in 12:4. The apostle's word here did not sanction their confused pursuings; rather, based on the fact of their confusion, he exhorted them to seek to transcend and thereby to excel in the midst of their confusion.
