Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church.
Zealous - emulously desirous.
Of spiritual gifts - literally, 'spirits;' i:e., emanations from the one Spirit.
Seek that ye may excel to. Translate, 'seek that ye may abound in them to them to the edifying,' etc. Seek to have not only tongues, but also interpretation and prophecy.
