Gustave, to answer your questions I believe I am in a better position to answer your questions than Phkrause since I have read most of his material, and consider his interpretation of the apocalyptic prophecy using God's four natural laws, which He built in them, the most accurate to date. But he has published teachings on all of the bible and was very astute, humble, and loved the Lord with all of his heart, and was open to progressive truths to his very end.
Yes, in his early years, (late 8o's) he thought since the Jubilee Calendar as he reasoned might come to a end in 1994, the return of Christ might be shortcoming. He made it clear that no prophecy pointed to that date but that was his reasoning. People made a big ta-do out of it and said, He said, Jesus would return in 1994. So most people got a negative view of him through word of mouth, first second, or third down the line, without reading any of his books or watching any of his many videos.
Is it not amazing how one negative comment about an individual can be recalled years latter when that individuals name is brought up, such as in the case of Phkrause. Mr. Wilson passed away going on three years now. But his ministry continues. www.wake-up.org. Consider checking it out. If you would like to understand the basic events taking place through the tribulation based on the prophecies of Rev., and using "God's four natural law," to interpret them, go to, Youtube" and type in, "Are You Ready For Coming Events." Its 18 minutes in length.
In answer to your last question Gustave, I have never heard of such a statement, and know that Larry would not have made such, knowing Christ did not sin while here on earth.
