I have been thinking about healing and other gifts recently too. Being raised a JW I always thought that healings were either fake or from Satan.
For the past couple of months I've been going to an Apostolic church. I'm really impressed how they follow the bible, including placing huge emphasis on Matt 28:19,20 and rely on the Spirit to help the great commission.
People within the church speak in tongues and prophesy, but they very rarely speak in tongue at church itself. I asked the pastor's wife, she said it's done more in private. I read 1 Corinthians 12 and 14 on it, and the bible says that tongues should only be done during meetings if there's an interpreter, so that's what they do. They do prophecy in church occasionally.
Anyway, starting next month the subject being studied at the Life Groups (Cell Groups) is 'The Gifts of the Spirit' - on what they are and how they are used.
I'm looking forward to learning more about it. I haven't seen any healing take place, but I know that as a church they believe it can happen. From what I've seen, it really looks as though they are genuine and have God's blessing.
I agree that sometimes people can be carried away with emotion at healings or there can be fakes or an emphasis placed on money. But I don't think all healings should be dismissed.
The early apostles could heal and though the bible says the gifts will end, and love will always remain, it doesn't give a date and time as to when the gifts end and it doesn't say the gifts died out with the apostles. So until Jesus returns in whatever way that means, I feel the gifts of the spirit can be used to show a church has God's blessing and to bring unbelievers to the truth.
