You may recall that during the time of Habakkuk, God raised up the Chaldean, a vicious and savage people, to deal with the Israelites. Would you say the Chaldean were a force for good?
God uses events to execute His will and perfect plan. That includes the Catholic Church, Joel Osteen, and ISIS. I wouldn't try to say one was "good" while the other "bad"-at least from God's perspective. The real question is whether they are following God's will as revealed through His word-not whether they are "a force".
I wonder who will be raised to deal with OUR nation?
We sure as HELL ain't on no path to repentance!
