Let's break it down, shall we? Starting with verse 4:
*There are different kinds of gifts, but the same Spirit.
*There are different kinds of service, but the same Lord.
*There are different kinds of working, but the same God works all of them in all men.
*Now to each one the manifestation of the Spirit is given for the common good.
*To one there is given through the Spirit the message of wisdom,
*to another the message of knowledge by means of the same Spirit,
*to another faith by the same Spirit,
*to another gifts of healing by that one Spirit,
*to another miraculous powers,
*to another prophecy,
*to another distinguishing between spirits,
*to another speaking in different kinds of tongues,
*and to still another the interpretation of tongues.
*All these are the work of one and the same Spirit, and he gives them to each one, just as he determines.
Two messages seem to jump out at me:
1. Not everyone has all the gifts of holy spirit, thus not everyone has all the manifestations.
2. Humankind is a community...no man is an island...we depend on each other...just as the different parts of our bodies make up the whole, so do individuals make up the community of mankind to work for the "common good."
So why do the TWI, CES/STF and CFFM organizations all insist that God wants all of us to speak in tongues? Given the verses above, nothing could be further from the truth. Chapter 14 goes on to tell us that it is preferrable to prophecy rather than SIT because SIT isn't of use to anyone who hears it except God, while those who prophecy "speak to men...for their strengthening, encouragement and comfort."
