When folks do what this man has done (or worse, reenact the crucifixtion), the world infers from it that the man is doing to endear him to God. The sacrifice, the pain, the suffering he endures all seem to be understood by the viewing audience as something needed to appease God. Irrespective of what he thinks of it.
Heck! You can "straight out" give the world the actual Gospel of Salvation, straight from the Scriptures and they'll infer something else, from that, too... LOL ...
There's nothing new here. :-)
But, as I said earlier, I'll bet that he has given the Gospel of Salvation to more people in the world, in his one-on-one interactions than you and me put together, by a long shot.
And, I did say I would be talking to him to find out exactly what his thinking is in regards to the Gospel of Salvation, and I'll bring up the "criticism" that you level... :-)
I personally don't see a problem with it at all, because I'm saying that he's giving the true Gospel of Salvation to people, according to the Scriptures, as he talks to them. However, I will let you know what I find out.
Numbers are immaterial. No where in the epistles do any of the writers intimate that doing odd things in public in order to talk to people is a measure of godliness. This "Billy Graham" mentality is unbiblical and detracts from the true message of the Gospel. And rest assured there is not going to be one person in the entire history of the human race that was among the elect that is left out at the last day. John 6:44ff.
