This is underscored by the following observations:
Since this is a debate board... lets debate your observations. We'll replace "paranormal" with "supernatural".
1. Most Real Christians™ seem very open to “supernatural” phenomena, often reminding other Christians that miracles, angels, demons, The Resurrection and Final Judgment are all beyond any “natural” explanation.
2. Most Real Christians™ seem fairly closed to deep scepticism of the “supernatural."
This demonstrates a lack of understanding of what Christianity is. In a nutshell - God created mankind as eternal beings who did not experience death. The first man, Adam, sinned and brought death - the only punishment for sin - into the world. This damned humanity for all time in that now everything experiences death. Jesus Christ came to earth to die in our place so that we could have eternal life. This is a free gift, but God does not impose the gift upon anyone. Those who believe in Jesus Christ, recieve the free gift of eternal life.
By it's very definition, Christianity is the belief in the supernatural. However, consider that what we see as natural today is not the "origninal natural". In fact, there was a time when death was the supernatural, and eternal life was natural. Indeed to God and the Angels, isn't the spiritual and eternal more real than this temporary life? God calls it a vapor. In the span of eternity is our ~70 years on the earth significant? Hebrews 11 is the 'fatih hall of fame'. It describes great men and women of faith in the history of Christianity.
Hbr 11:13 These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of [them], and embraced [them], and confessed that they were strangers and pilgrims on the earth.
14 For they that say such things declare plainly that they seek a country.
15 And truly, if they had been mindful of that [country] from whence they came out, they might have had opportunity to have returned.
16 But now they desire a better [country], that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city.
Like these, we believe that what we are experiencing now is not natural. It is the un-natural. It is a perversion of the original creation. To put it lightly, it is a great assumption to say that what Christians believe is supernatural, while what is currently observable is natural. The Bible gives us the details on how things began, how things were prior to the Curse (the corruption of the original design) and how things will be again in the future once that last great enemy death is defeated:
1Cr 15:26 The last enemy [that] shall be destroyed [is] death.
These things are not "beyond natural explaination". The 'nature' of 'natural' has simply been changed at present. In fact, the reality of death should only serve to confirm the scripture's validity. The Bible says that Adam sinned and death entered the world. It says that Satan has come to the earth to kill, steal, and destroy, and that he is currently the god of this world. Therefore at present, we should be able to observe the effect of this - and we do. We see death naturally everywhere.
3. Christianity seems to be expanding in The Third World and shrinking in the First.
It's obvious why, isn't it? Christians are out-evangelized in the First World, but have the upper hand in the Third World! For example, how many secular TV networks are there compared to Christian TV networks? How many bars, liquor stores, etc are there compared to churches? With the rampant humanism in American Public education system (evolution, homosexuality, etc) schools and universities are churches to humanism. With the ammount of money spent on sex, drugs, alchohol, etc, how can the ammount of money spent on preaching the gospel even hope to compete for the attention of perishoners?
Of course, people in third world don't have money to spend on such things. In most cases, missionaries to the 3rd world are being funded by those in the First. For example, lets say the good Baptists decide to go and build an orphanage in Peru. Through funding from the United States, they care for children and teach them God's Word. This is the equivalent of Budweiser setting up shop in a remote village you can't get to without a donkey and giving away free beer and water for a few generations.
These have nothing to do with being pre-modern, modern, or post-modern. There really is nothing new under the sun. It's simply a matter of effectiveness and effort. The church in most First World countries has compromised to humanism far too much. For example, you have many Christian leaders who support evolution -- an idea which directly contradicts the Bible. Why would anyone take what is said as genuine when the ones offering it don't even truely believe it? Why should anyone believe the Bible if it isn't authoritative and true?
