God IS doing something about evil--not the least of which is being patient with you and I about OUR evil! Even though He gets a lot of slander for...
not judging evil quickly, nevertheless many of us appreciate the fact that He didn't judge us too early, and that He gave us time to 'get right with...
Him'! In some cases, He actually will take consequences of evil choices and 'twist' them for the good of others...
Does this seem like a reasonably possible explanation to you?
