This passage is all about the millennial reign of Jesus Christ...
1 Cor 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.
9 For we know in part
(now), and we prophesy in part.
(now)
10 But when that which is perfect is come
(Jesus/Millennial kingdom), then that which is
in part(now) shall be done away.
11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.
12 For
now we see through a glass, darkly
(in part), but then
(future) face to face: now I know in part
(partial gifts), but then shall I know even as also I am known.
(end of gifts, then see Jesus face to face)
Remember the beginning of the chapter....
1 Cor. 1:7 So that ye come behind in
no gift;
waiting for the coming of our Lord Jesus Christ:
8 Who shall also
confirm you unto the end, that ye may be blameless in the day of our Lord Jesus Christ.
(at the end of the age, then the gifts of chapter 12 will not be needed)
