Not *uncomfortable with* but clearly identified ad those belonging to the apostolic period. Signs, wonders, and miracles were primarily for the apostles and their companions (Hebrews 2).
This is faulty reasoning. The author of Hebrews says that when the gospel was first preached among his readers by them that first heard the Lord, it was accompanied by signs and wonders. We also see in Acts this happening in Jerusalem. But it happened again in Samaria (and we do not know that Philip the evangelist or Stephen ever knew the Lord before the resurrection). And it happened again in Joppa, and it happened in Ephesus and Malta and elsewhere. And we read of gifts being given to the church.
The passage does not say what you think it is saying.
You can walk into any church of any denomination today, and this is exactly what you will see. All those who claim to be apostles and prophets today are charlatans.
The title of apostle, etc. is a controversial issue and continuationists have different views on this. But be that as it may, you can walk into many churches where you may actually witness prophesying.
This is also something you should be careful about with your broad-brushing here, because Jesus warned those who accused the Holy Spirit by Whom He was casting out demons of being a devil, that whoever speaks a word against the Holy Ghost will not be forgiven in this age nor in the age to come. Paul also commands, "Despise not prophesying. Prove all things. Hold fast to that which is good." If you reject prophesying out of hand-- even if it is because of your (man-made) theological presuppositions-- you can be setting yourself up to disobey the command 'despise not prophesyings. Obeying the word of God is more important than your doctrinal speculations.
This in no way excludes direct divine miraculous intervention through prayer (or sometimes even without prayer). Divine healing is now through prayer (James 5).
There are many means through which we read in scripture that God chooses to heal. Answering prayer is one of them. James 5 is a wonderful passage that actually contains a promise of healing if the conditions are met. The elders must pray the prayer of faith. But there is no indication that James 5 (which might have been written quite early) was intended to supplant other scripture on healing, for example I Corinthians 12 which says that gifts of healing are among the gifts the Spirit distributes to the church.
BTW no one *does away* with miracles. But bogus miracles are being performed by some to claim they have special powers. These same people also want poor gullible Christians to make the preachers prosper and maintain lavish lifestyles.
I haven't had a chance to read it. I do not know if you have ever heard of evangelical theologian Craig Keener or read his Bible commentary work. He started writing a footnote on miracles, and it turned into a 1200+ page book entitled 'Miracles.' It argues against Hume's argument that miracles are not real because they go against normative human experience by reporting the fact that numerous Christians have reported miracles in their experience. It contains numerous historical and modern examples.
You should be careful about basing doctrine on your experience (or lack thereof in this case). If you have not seen miracles or those around you have not experienced them, that does not mean they don't happen. If they are rather rare, that does not invalidate the teaching of I Corinthians 12 that the Spirit gifts individuals as He wills. If the Spirit did not will to gift an individual in this way for 100 years, you have no right to say that He no longer does so and to blindly accuse someone He does so gift of being a charlatan when you hear of the miracle based on your conclusions based on your own experiences. Scripture is not the servant of your experiences and neither is the Holy Spirit.
