What is ours by promise is not always ours by experience.  We are often too stubborn to receive the promise of God's goodness. All the children of Israel that God delivered out of Egypt were promised the Promise Land but only two entered. Only Joshua and Caleb had the courage and were able to enter in. Good truly tests us more than evil. And a lot, if not all of what God promises you, you must fight to possess. The harvest and entering the Promise Land is a lot of hard work.
