One other thing that gets me doubting is the whole book of Acts and the other "signs" that the apostles speak of. If these kinds of things were possible by believers...why don't these things happen anymore? Why have I never seen or felt the holy spirit come upon the way it is described as coming onto the converts of the early church? Did they mean what they said more than I do? Why doesn't anyone honestly expierence these things anymore? Why don't we ever hear about people being healed miraculously by other people? Why don't we see people coming back to life? If the things that were true then are supposed to be true today...why are things so different?My response is this:
First of all, I think we need to escape from the Modern mindset that reason defines reality. Reason is a facutly of man, and as such God is not subject to it. Therefore we can never reasonably draw the conclusion that something God is supposed to have done must be untrue soley because it is unreasonable. Ironic, huh? Instead we have to approach all things about God and His nature with the mindset put forth in Isaiah 55:8-9 :
8 "For my thoughts are not your thoughts,
neither are your ways my ways,"
declares the LORD.
9 "As the heavens are higher than the earth,
so are my ways higher than your ways
and my thoughts than your thoughts.
It is the height of human arrogance to believe that we can understand why God does what He does, or presume to say that He should act a different way than He does.
Furthermore, I don't think that the apparent lack of miracles, assuming that it really is universal and not just in my life and yours, is not unbiblical. Look at the old testament. It is full of people preforming miracles, but they are all years apart. What happened between Elisha and the other major Prophets? What happened between Hosea and Jesus? I'm sure the people then were also saying "Where are all these miracles people are always talking about? How come no one is doing miracles now?" It may be that God only preforms such miracles through people at certain times -- specifically times when they will achieve some end that we cannot understand. It may well be that a time may come again when there are many miracles happening often.
Finally, there are people today that claim that such miracles do still happen. As I'm sure you are, I am always skeptical of these claims. Especially by certain groups. However, it may be that such miracles occur where they are appropriate, according to the mind of God. It may simply be that your life and mine have never intersected those times. There were plenty of people in Israel, as small a country as it is, who never saw one of Jesus' miracles. Yet that doesn't mean they didn't happen. Now we're talking about a global scale. Just because neither you nor I ever comes in contact with a miracle or even someone who has seen one (although, as I said before, I have heard a few first-hand accounts, at least one that is mostly credible) does not imply that they are not happening. That would be a wholly unreasonable conclusion to come to. It is notable to mention that there isn't really a sense in Acts that every Christian was able to preform the miracles, mostly only Apostles. An apostle is, literally, "one who is sent." It is also important to note that The 12 Disciples were not the only apostles. Barnabas and Silas are both specifically called apostles. Apostles are people with the highest "calling" in the church who are specifically sent by God to do some work -- not all who are called to evangelism or missions are necessarily apostles. It would not be unreasonable to believe that only Apostles, as those with the highest calling, are given the gift to preform miracles all over the place. That is just my own conjecture, I have no further reason to believe that than it seems like they account for the majority of the miracles in the new testament and it makes at least a little sense.
All that being said, I think that it is unreasonable to use reason as a measurement of truth when God is involved. God can do things that seem unreasonable, or even are unreasonable. Furthermore, the lack of miracles around you may not be so unreasonable at all. The experience that you and I have had does not warrent the conclusion that the accounts in Acts are false. One final point concerning the fear that the Bible has been significantly altered is that the Dead Sea Scrolls were very close to the current manuscripts we were working with at the time they were found, so any significant changes to the old testament were done before 200BC. I suppose that you could claim that people since then changed the new testament letters and not the old since the old were already canonical, but the fact that they didn't change the old provides at least some hope that they left the new generally in tact -- at least enough that they didn't take the truth out of them.
