He is the great King and the mighty God who gives victories to the unworthy sons of unworthy Jacob. God is the one who delivered His people and thoroughly confused their foes! No wonder the people kept boasting of their connection with Him, kept saying they would never cease to thank Him!
This eliminates NO. (and You've got to be kidding me) Of course, we would like a God who never says NO, flat out and without explanation, but I think He occasionally does that and we have to recognize that as a sovereign He has the right to do so.
