1 Corinthians 12:7-11

7 But to each one is given the manifestation of the Spirit for the profit of all.  8 For to one is given through the Spirit the word of wisdom, and to another the word of knowledge, according to the same Spirit;  9 to another faith, by the same Spirit; and to another gifts of healings, by the same Spirit;  10 and to another workings of miracles; and to another prophecy; and to another discerning of spirits; to another different kinds of languages; and to another the interpretation of languages.  11 But the one and the same Spirit works all of these, distributing to each one separately as he desires.

1 Corinthians 14:1-5

1 Follow after love, and earnestly desire spiritual gifts, but especially that you may prophesy.  2 For he who speaks in another language speaks not to men, but to God; for no one understands; but in the Spirit he speaks mysteries.  3 But he who prophesies speaks to men for their edification, exhortation, and consolation.  4 He who speaks in another language edifies himself, but he who prophesies edifies the assembly.  5 Now I desire to have you all speak with other languages, but rather that you would prophesy. For he is greater who prophesies than he who speaks with other languages, unless he interprets, that the assembly may be built up.
