If true, this is a shocking situation. Haggard is the President of the National Association of Evangelicals and is probably one step down from James Dobson as America's best known evangelical leader.
It has been reported for many years that Haggard was an Open Theist. I was always uncomfortable with his leadership because of this - not to mention his relationship with George W. Bush.
In response to these allegations, Haggard has voluntarily stepped down from all his leadership positions until the matter has been sorted out. This should not be interpreted as an admission of guilt, since I would probably do the same thing if I was innocent of such charges.
We should pray that he relies upon the goodness of the sovereign Lord.
