Fast-forward to the 7:00 minute mark before this video disappears from the Internet again:

The Nation's Max Blumenthal provides some background:

On September 20 and 21, I attended services at the church Sarah Palin belonged to since she was an adolescent, the Wasilla Assembly of God. Though Palin officially left the church in 2002, she is listed on its website as “a friend,” and spoke there as recently as June 8 of this year.
I went specifically to see a pastor visiting from Kiambu, Kenya named Thomas Muthee. Muthee gained fame within Pentecostal circles by claiming that he defeated a local witch, Mama Jane, in a great spiritual battle, thus liberating his town from sin and opening its people to the spirit of Jesus.
Muthee’s mounting stardom took him to Wasilla Assembly of God in May, 2005, where he prayed over Palin and called upon Jesus to propel her into the governor’s mansion — and beyond. Muthee also implored Jesus to protect Palin from “the spirit of witchcraft.” The video archive of that startling sermon was scrubbed from Wasilla Assembly of God’s website, but now it has reappeared...Next week, I will post an exclusive video documentary [on my blog] that will shed further light on Palin’s relationship with Muthee and the religious right in Alaska. Stay tuned.
