When God guides God provides. The calling of God is the enabling of God.
Therefore if we are attempting to do something and God is not even in it, if He is closing the door on it. Are we to stubbornly continue to push forward with our own agenda? Would not it be better to step back and rethink our position? Why misuse the resources that we have on projects that God is obviously not in?
