Thank you for your response Quix. Out of all the doctrine I believe this requires the most extra-biblical study. Two proofs I find convincing are:
1. The United States has always considered itself a Godly, Christian nation. Not quite a theocracy, but with a strong sense that God is guiding and blessing our nation. Manifest destiny comes to mind. A very large percentage profess belief in God.
2. Circumcision - Although it's not a salvational issue under the new covenant, the circumcision rate in the United States is still somewhere in 70% range...down from a high or 90 something percent. I think it's very interesting that the circumcision rate began to rise as the United States came into prominence in the world. Circumcision is of course what marked a physical Israelite as an Israelite. This of course isn't proof, but is interesting speculation.
UFO etc....I think it's a very real possibility that when Christ returns "in the clouds" that it will be portrayed as an alien invasion and this is why so many will fight against him. But again, this is just my opinion so take it with a grain of salt. :-)
Dear Charismatic etc Believers . . . it might be fruitful for The Kingdom to help keep this bumped for a while.
