The context of 1 Corinthians 12-14 is maturity, growth, completion of the saints to the glory of God. In fact, when Paul began his teaching on the gifts of the Spirit, in chapter 12, he compared them to the human body's parts and proper functioning. Why would the parts of the body, and with them their functions, be done away simply because scripture was partially revealed? The body of Christ must still function and nowhere does scripture claim to take the place of the body's workings. In chapter 13, Paul began by showing that loveless use of the gifts is unprofitable, then taught about love, then showed the maturity brought about by love. Children are selfish; mature adults love selflessly. The coming of the perfect coincides with Ephesians chapter 4, wherein Paul stated that the equipping gifts were given to the church UNTIL the body has grown unto Christ's full stature...and the body builds itself up in love. When the gifts are used selflessly, ie for others' benefit, then they are being used in a loving manner and the body grows closer to the Head. There is no drunken reeling and staggering to what I'm saying. It is quite methodical and scriptural.
