As the word tells us our belief is counted for righteousness.
As we read the word we should read all the promises that are obtained by the righteous.
If those promises aren’t obtained it is not that God has changed his mind but that our level of belief is not as great as we try to claim. Our level of belief grows just like following a map to a destination increases the closeness to our destination. There are many that deny that as truth because they have followed their map and yet not obtained the promised destination. Perhaps the map we have followed is not completely correct?
If we are not obtaining what God promises we can change God or change our self. A proud man tries to change God, which is why they shall fall.
