What do you think of these gifts?

"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." (1 Cor 12:8-10)

The Bible speaks of various gifts of the Holy Spirit, as indicated above, which are contested by some believers, as even being applicable for today. We think this is unfortunate because these are actually very powerful gifts. Albeit, they may have been misused by many. And so our goal is to teach the correct application of these gifts. How do they actually work?
