>On the contrary, I think it is God's prerrogative to do whatever He pleases.
I agree with you there.
Basically, you led off your earlier comment by saying "I believe that God's laws have to change,..." which seem to say God is somehow reacting to humanity. God, in his omniscience, would have known everything beforehand and thus he is not at the mercy of our actions. In rereading your comments, perhaps you did not mean this in the way I took it.
As for Matthew 5:18, I'll have to study more on this because clearly this is not as cut and dried as I thought.
