I saw many of Jack's shows with Rexella. Very entertaining.
I saw him in the '90s and I have seen it in the past few years and he hailed from and I believe broadcast from Michigan.
Bible prophecy is of importance to many. What he'd say is probably a bit similar to Hal Lindsay.
Thanks Jack, you will be missed. Sorry to hear this.
W'pedia's page for Van Impe is fairly informative. For a site that is reliably Lib-Prog in socio-political matters, it's interesting that no scandals - moral or money - are mentioned. He and Rexella, who survived him apparently, married before I was born. 65 years' marriage isn't Guinness Book of World's records grade, but definitely impressive.
From the W'pedia page, Van Impe was definitely into Dispensationalist, Pre-Millennial, Pre-Tribulation eschatology, and made that the focus of his ministry. I'm Pan-Mil, Pan-Trib - it'll all pan out in the end,

. Hal Lindsey is of similar views. I thought Lindsey was younger than Van Impe, but he is actually a year or two older.
It's disappointing to me that Van Impe started or repeated the ludicrous claim that Rick Warren was teaching/advocating what Van Impe and others have called "Chrislam" (merged Christianity and Islam). Obviously 8-10 years after the fact gives something close to 20-20 hindsight, but I said on another discussion site around that time that it was a ridiculous claim. Gnat-screening heresy-hunting is a trap to which Fundamentalist seem somewhat more susceptible than most Evangelicals, and this is far from the worst I've seen.
