First, a clarification - Bill Keller did not post this message on this discussion thread, I received the devotional from him, along with a press release statement that he wanted the message put out about calling Americans to 40 days of prayer and fasting starting May 1st, 2004.
Now speaking on Bill Keller's defense, I do not believe he considers himself a prophet to the degree that you name Jim Jones, the Branch Davidians, etc - there are always cults out there seeking to promote their own agendas. (Honestly, if I was to post some of the other devotionals that I have received, most of common day Americans would think Bill Keller was a lunatic for the way in which he thinks. He even comments that some issues are so inflamitory, he is bombarded with attack emails.) (Like Freepers don't know what that is like.) :^)
Personally, I'd like to see Congress turned upside down and shake out all of the intrenched liberals and replace them with upstanding people who believe in the original intent of the US Constitution! Maybe then this country would get back to it's Judeo-Christian foundation laid down by our fore fathers.
I am not a prophet or theologian myself, although I have read quite a bit on what will transpire at the end of this age - although I do not know the timing of such matters.
In the Garden of Eden, Adam originally received from God complete dominion and authority over the entire creation on earth. (Genesis 1:26) He also had dominion over Satan, but was "bribed" into a deal with Satan after Eve was seduced to sin. Now Satan legally holds the title deed to this world, a title and authority that was delivered to him by the original recipient, Adam. The same authority was offered to Jesus by Satan, for the small price or worship. (Luke 4:5-7) Jesus did not dispute Satan's claim that this world was delivered to his authority. Jesus did not even challenge his jurisdiction, but flatly refused Satan's offer, choosing obedience to God and the plan for his blood to be poured out as the atonement for sin. (Ephesians 1:4)
God gave man free choice, and God cannot change - sin is and always will be sin to Him. Only through the blood of Christ and his sacrificial death do we have forgiveness and grace. God lets people choose their course, only by prayer and intercession can the mind of God be changed - as it did when Nineveh was supposed to be destroyed as Jonah talks about.(Jonah 3:4-10)
