One of the top three shifts that I've gone through in regards to my own knowledge of God is in the realm of Eschatology (aka the end times, aka the second coming of Christ.)
Thanks to JT over at Between Two Worlds for pointing out this article by Kim Riddlebarger. The article is a fantastic summary of what I now think and believe to be the truth about when Jesus is coming back, who the antichrist is and what to expect from life between now and the last day(s). (I also give much credit to my Friend and Pastor Tim Porter for steering me right in proper end times thinking.) I highly recommend you take three minutes to read the article.
