However, God later clearly stated and revealed to Jonah exactly what He had done and why. Robertson states he doesn't know why God did not act in the manner He said He would.
Isaiah told Hezekiah that he would die shortly. It didn't happen. So there again goes your "golden rule".
However, in Isaiah chapter 38 God again clearly tells Isaiah that He has changed is mind as a result of Hezekiah's prayers and added 15 years to his life.

I stand by the standard clearly articulated in the Bible.
So, that's irrevelant as to why your hard and fast is wrong.
However, in Isaiah chapter 38 God again clearly tells Isaiah that He has changed is mind as a result of Hezekiah's prayers and added 15 years to his life.
Once again, totally irrevelant as to why your hard and fast is wrong. The simple fact is that sometimes people can choose to respond to whats been said so that things change.
