Wrong. This is just David`s perspective. When a person or nation rebells against they Lord they do things which bring destruction upon themselves. In this case, enemy nations would see the weakness of israel and take advantage of it. The Lord did not turn against Israel, Israel turned against the Lord.

Even under Grace it is imperative that believers understand the power of the SpiritualLaws of the Lord. They are still in effect to produce blessing to the obedient and curse to the rebel.

Our Lord does not vascillate between love and anger. He is love but His laws implement His righteous judgment.
