Dr. Caner's testimony before 2001 is something that his critics and allies alike would like to see, but finding a copy of it is proving elusive. (Photo at left, circa 2001, is hosted by middlecreekbible.org, I'm just linking to it.)
First, here are some post-9/11 testimonies.
Testimony on the 700 Club
According to a transcript, in one appearance on the 700 Club, Caner appeared to indicate that he was led to Christ, then his brothers, then his mother, and finally his grandmother.
What's wonderful is that day my father disowned me, but both of my brothers accepted Christ. My younger brother teaches at a seminary, I teach at a Christian College, my middle brother is a strong Christian and a member of a church, our mother accepted the Lord and is married to a church planter, and my grandmother accepted the Lord right before she died.(Source)
Testimony in Unveiling Islam
The Caner brothers' book, Unveiling Islam states that Jerry Tackett was "an active member at Steltzer Road Baptist Church." Jerry invited Ergun Caner to revival services there. (Unveiling Islam, p. 18) Unveiling Islam goes on to state that on some unspecified day, which was a Thursday, Ergun came to Christ. Then, at a later unspecified date, Erdem came to Christ in the basement of "their home." Next, "the following year," Ergun invited Emir to a revival service. It states, "On November 4, 1982, Emir was born again." The book goes on to state that "In 1982, Ergun surrendered to the gospel ministry. It was the last time he saw [his] father for seventeen years. Acar disowned his sons ... ." (Unveiling Islam, p. 19) Unveiling Islam later states that it was Jerry Tackett who led Ergun to Christ and that it was Clarence Miller, the pastor of the Steltzer Road Baptist Church, who led Emir to Christ (Unveiling Islam, p. 21).
Testimony on the John Ankerburg Show
On the John Ankerburg show, Ergun Caner states that "a year later" than his own conversion, both his brothers accepted Christ (link to clip).
Testimony in Sermon "Church House to Jailhouse"
On the "Living with Joy" Radio interview, Ergun stated:
Finally he invited me to a revival. And so I walked in to Stelzer Road Baptist Church in Columbus, Ohio in full gear with a coat on. ... I stepped out of the second pew, walked to the front. Clarence was preaching and he had his eyes closed. "What?" I said, "Isa bin Allah. I believe Jesus is God. I want saved." And he said, "Could you wait for the invitation?" I said, "No." He led me to Christ standing in front of the whole church. ... I went home and told my father. I said, "Abi, I am born again. I'm saved." It was November 4, 1982 and it was the last day I saw my father. ... A year later both my brothers got saved.(transcript here)
Testimony of Tim G.
Tim G. has claimed to have some inside knowledge of the Caner situation. He states:
The man who led him to Christ is still alive. Clarence Miller. He has attended all his inaugurations and graduations. If he or Emir were two white boys lying about being devout Muslims, do you really think he would abide that?(source)
Interestingly, Tim G. also claims that Ergun Caner's mother was adopted, that she was not Swedish, and that the name of Ergun's grandmother is "Maria Eleonora Lindberg" the woman to whom Unveiling Islam is dedicated. Other things that Tim G. says (such as the reference to Ergun's two half-sisters) appear to be accurate. (Wade Burleson identifies Tim G. as Tim Guthrie, later in the comment box.)
Before 11 September 2001
However, before 11 September 2001, what was Ergun's testimony? It is hard to say. The image below (which I'm linking to ... it's hosted at archive.org) states that "Ergun Caner is the son of a Muslim clergyman. He was led to Christ by his grandmother and is currently completing his Ph.D. at the University of South Africa." The accompanying April 2001 newsletter states: "As you will see in the brochure, Dr. Caner is the son of a Muslim clergyman. His grandmother led him to Christ, after which his father disowned him." (source)
There are some inaccuracies in the poster for the conference. For example, Dr. Caner was at that time apparently studying for a Th.D. not Ph.D, and his father was not a Muslim clergyman, as far as we can tell.
