These institutes don't claim be be wrought of God and part of his handiwork.
God's plan for these "institutions" is not hidden and his patience is not finite when it comes to their sin
As far ORU, the moment this "institution" no longer can be used by Him to further his ultimate plan, they no longer will be able to sustain themselves. His hand will be off them.
You can make such a statement re Islam with a straight face? Simply because God allows evil people to flourish doesn't mean He's using them or blessing them.
God allows all forms of evil to exist, Oral Roberts' Enterprises included. It doesn't mean He has a purpose for them.
