The Bible is chock full of religious leaders calling true men of God false prophets (and worse), including Jesus himself. Consider it a badge of honour.
The mere fact that I've seen interpretation of tongues in the church is not what makes it true. It's in the scriptures (1 Cor 12:10) and that's what makes it true.
Of course Christians can get revelation from God. There are 3 different revelation manifestations listed in 1 Cor 12:8-10. Word of Knowledge is learning something that is not possible to learn via your 5 senses. God telling you your friend needs help certainly qualifies. Word of Wisdom is what to do with that knowledge, in your case, pray for the guy. What could possibly be wrong with that? Nonetheless, some will find fault. Ignore them. The third revelation manifestation is Discerning of Spirits. Wouldn't you think that those manifestations just might be useful in a Christian's walk? I'd sure say so.
All revelation you get from God will always line up with the scriptures. It will never contradict them.
Speaking in tongues is for one's private prayer life. Among other things it edifies or builds up the individual believer (1 Cor 14:4). However, when in a public gathering (church or other fellowship meeting) if one speaks in tongues that same person must interpret so the whole assembly receives edification (1 Cor 14:4). The manifestation of prophecy is equal to tongues with interpretation and it also edifies the whole assembly. Read 1 Cor 14:4-5. The reason verse 5 says prophecy is "greater" than tongues with interpretation is because it indicates a more mature or developed group of Christians. Tongues is a "sign" to them that don't have much believing (1 Cor 14:22), so it is most useful in a group of new believers. A group of more mature believers do not need that sign, so they can go straight to prophecy. Both tongues with interpretation and prophecy are messages to or from God to edify. Prophecy is not necessarily about the future.
There is one gift, holy spirit. We can't see spirit with the five senses so God made the nine manifestations available so the believer can operate the power of God in the senses realm. It is possible for each believer to operate all nine manifestations. One need only to be taught and believe. Indeed the nine manifestations are a big part of the whole armour of God (Eph 6:11-13).
Why Christians deny the ability to get word of knowledge, word of wisdom, discerning of spirits, faith, healing, miracles, and prophecy is beyond me. I'm sure I'll be called on the carpet for even suggesting a born again believer can operate all nine manifestations, but, oh well. The Bible clearly says we will do the works that Christ did and then some (John 14:12). Did he not do all the things listed in 1 Cor 14:8-10 with the exception of tongues and interpretation of tongues (they weren't available until Pentecost)? According to John 14:12 the only reason someone would NOT operate the manifestations is because they don't believe everything Jesus said. I'll probably get flamed really good for saying that, but I stand by the plain language of John 14:12 (He that believeth on me, the works that I do shall he do also) regardless of what I'm called. God calls me his dear child and that's good enough for me.
I'll be praying for your continued growth in the knowledge of God and his word. He wants you to know (Eph 3:16-19, 2 Pet 1:3, et. al.).
You said................
"Why Christians deny the ability to get word of knowledge, word of wisdom, discerning of spirits, faith, healing, miracles, and prophecy is beyond me."
That is easy.
1 Corinthians 13:8 says so....................
"Love never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish."
The gift of prophecy in the apostolic church was not forthtelling the truth of the written Word, but declaring truth which had been specially and directly revealed by the Holy Spirit to the "prophet" in the absence of the written New Testament revelation. It was, like the gift of "knowledge," the sovereign enduement of special direct revelation of truths now contained in the canonical New Testament Scriptures.
Both "prophecy" and "knowledge," therefore, were of necessity "tie-overs" to supply the church's practical needs until the New Testament Scriptures became available. In exactly the same way, although not so directly and indispensably useful as "prophecy" and "knowledge," were tongues, unless interpretation of the tongue's message was present.
"For we know in part, and we prophesy in part." 1 Corinthians 13:9.
"In part [Greek-piecemeal, partially, bit by bit] we know and in part [same word] we prophecy." The apostolic gift of knowledge by direct inspiration because it received truth only partially and piecemeal- here in this church assembly a little, there in that church assembly a little, the gift was incomplete and gave only a part of God's truth. The same was true of declaring the truth of the partial and piecemeal revelation. Therefore the gift was lacking and temporary until the complete revelation was given which is the complete New Testament.
"But when that which is perfect is come and reguardless of what anyone may say, the word in Greek-
'to teleion', means the completed and final THING, which can only mean 'the New Testament Scriptures'. Then that which is in part [partial or piecemeal revelation through the gift of directly inspired prophecy and knowledge before the New Testament was given] shall be done away with [shall be superseded, rendered unnecessary and meaningless, because no longer needed and so shall be canceled and done away with]."
This is the same Greek word used of "prophecies" and "knowledge" in verses 8 and 11, "I put away childish things."
The Apostle Paul employs two graphic illustrations to make his point. The first is that of a person growing up from up from childhood into adulthood. The second is that of looking into a mirror to see oneself. Concerning the first illustration the apostle says: "When I was a child, I used to speak as a child, I used to think as a child, I used to reason as a child. But when I became an adult I put away childish things."
He is contrasting "that which is perfect" [the completed, final, and fully authoritative Scriptures of the New Testament], which he likens to an adult male, with "that which is in part" [the piecemeal incomplete revelation directly from the Holy Spirit through the exercise of prophecy, tongues, and knowledge], which he likens to a child.
Having to depend upon prophecy, tongues, and knowledge for instruction and edification until the completed New Testament became available was similar to childhood in the experience of the church. Speaking in tongues, for instance, had a purpose in the apostolic church like the chatter of the child has a similar purpose in childhood and like the child's thinking and reasoning processes have a similar purpose in his growing up into manhood. The same was true of knowledge and prophecy. But now that the church has grown up into adulthood, so to speak, with a complete revelation given it, it has 'put away childhood things'; that is, it has set aside as superseded [same word as in verse 8] tongues, prophecies and knowledge, as having no needful place in its adult life, and belonging only to its childhood requirements.
