Tomi, I'm glad you felt blessed by some of Armstrong's teachings. If one can gleem Truth from any TV or radio evanglist and not be sucked in by some of the false things they sometimes teach, I have nothing bad to say about it. I would however be aware of the legacy he left behind which did much damage to believers everywhere. The Worldwide Church of God however did confess their sins and repented, once they were delivered from the Armstrong family's grip. May be a first...I don't know.
He is only a man and we all at times fail in our words and actions....but the real test of a person is if they are willing to repent and turn away from falseness.
