The purpose of miraculous signs was to being about the complete, whole word of God. (The KJV uses the word "perfect" that means complete. whole).
The problem with your theory is that the Bible does not teach this. There are also multiple purposes for various gifts. Speaking in tongues serves to edify the church when accompanied by interpretation. It edifies the speaker. It serves as a sign to them that believe not (a fulfilment of 'and yet for all that, they will not hear Me.') Prophecy serves as a sign to them who believe. It also comforts, edifies, and exhorts. It testifies of Jesus. The miracle of feeding the five thousand showed a number of things, including God's provision. Feeding multitudes helped communicate that Jesus is the Bread of life and served as a backdrop for one of His sermons on it. Jesus reminded the disciples of it when they forgot to buy bread. But it also served the practical purpose of feeding the people right then and there.
Signs and wonders confirmed the word as it was preached, also. The Bible doesn't teach that signs and wonders confirmed the Bible one time for all. If we read Acts, signs confirming the word is a repeatable thing. The word can be preached over and over again. Signs and wonders can be repeated over and over again. When Peter went to Joppa, we don't read where he said the word he was preaching was already confirmed in Jerusalem, so he was just going to leave Aeneaus crippled. No, he did a miracle again. The Gospel continues to be preached to unsaved individuals, unreached individuals, unreached villages, and unreached peoples.
The signs were also used for confirmation of that word. Since the word of God was completed and confirmed by the apostles by the end of the first century, then those signs fulfilled their purpose so they ceased, vanished away as Paul said they would.
Again, this is a man-made theory. The didactic teaching of scripture trumps you theory. For to one is given one gift by the Spirit, and to another, another gift like we read in I Corinthians 12. Your theory doesn't cancel out that verse. Man-made theory doesn't cancel scripture.
Not only is my proof in that the bible teaches miraculous signs have ceased, but proof also lies in the fact that 100% of the people I have met that claimed that God worked miraculous signs through could not perform a single one.
For one thing, the Bible doesn't teach that, and you haven't demonstrated it. You have a theory about the Bible, not the teaching of the Bible in you corner.
You also assume that someone who works miracles does so at will, which isn't consistent with scripture. The apostles had done miracles, but they prayed for God to stretch out His hand to do signs and wonders. Apparently, they were dependent on the Lord for the miracles to occur. It wasn't just something they did purely automatically, but something they did in cooperation with God. The KJV says that Jesus could do no mighty works in His home town because of their unbelief.
There is also a major problem with your logic. Just because you haven't seen something doesn't mean it doesn't exist. That's the problem with someone who bases doctrine on experience like you are doing, at least partly, according to your post. At least someone who has seen a vision has a logical reason to draw from his experience to say that visions are real. But if someone hasn't seen a vision and concludes from that that they are not real, that's just irrational and illogical. If you haven't seen anyone work a miracle, that doesn't mean that miracles do not occur at time.
O\They could only offered excuses as to their inability to do any.
I made the offer in other threads in times past and will make the offer here again that I will pay out of my pocket first class travel expenses (back and forth) to anyone who claims that God does miracles through them to come to city I work in to a 12 story, 1000+ bed hospital and empty it out. It will cost that person nothing but a little of their time......but what is a little time compared to all the human pain and suffering that will be ended?[/QUOTE]
