WEDNESDAY WORD DAY

1Co 12:8  For to one is given by the Spirit the word of wisdom; to another the word of knowledge by the same Spirit; 
1Co 12:9  To another faith by the same Spirit; to another the gifts of healing by the same Spirit;


by ... by ... by — The first in Greek is, “By means of,” or “through the operation of”; the second is, “according to” the disposing of (compare 1Co_12:11); the third is, “in,” that is, under the influence of (so the Greek, Mat_22:43; Luk_2:27).


1Co 13:8  Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.

1Co 13:8
never faileth — never is to be out of use; it always holds its place.
shall fail ... vanish away — The same Greek verb is used for both; and that different from the Greek verb for “faileth.” Translate, “Shall be done away with,” that is, shall be dispensed with at the Lord’s coming, being superseded by their more perfect heavenly analogues; for instance, knowledge by intuition. Of “tongues,” which are still more temporary, the verb is “shall cease.” A primary fulfillment of Paul’s statement took place when the Church attained its maturity; then “tongues” entirely “ceased,” and “prophesyings” and “knowledge,” so far as they were supernatural gifts of the Spirit, were superseded as no longer required when the ordinary preaching of the word, and the Scriptures of the New Testament collected together, had become established institutions.
