"Having then gifts differing according to the grace that is given to us, whether prophecy, let us prophesy according to the proportion of faith;"
I Corinthians 12 talks more about gifts from above, and we should use all the gifts given to us (you should read this whole chapter):
4 Now there are diversities of gifts, but the same Spirit.
5 And there are differences of administrations, but the same Lord.
6 And there are diversities of operations, but it is the same God which worketh all in all.
7 But the manifestation of the Spirit is given to every man to profit withal.
8 For to one is given by the Spirit the word of wisdom; to another the word of knowledge by the same Spirit;
9 To another faith by the same Spirit; to another the gifts of healing by the same Spirit;
10 To another the working of miracles; to another prophecy; to another discerning of spirits; to another divers kinds of tongues; to another the interpretation of tongues:
11 But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
12 For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ.
And here, Thessalonians 5 tells us not to waste such gifts:
19 Quench not the Spirit.
20 Despise not prophesyings.
21 Prove all things; hold fast that which is good.
22 Abstain from all appearance of evil.
1 Timothy 4 again tells us not to waste spiritual gifts:
14 Neglect not the gift that is in thee, which was given thee by prophecy, with the laying on of the hands of the presbytery.
15 Meditate upon these things; give thyself wholly to them; that thy profiting may appear to all.
16 Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee.
