The true follower is completely dependent on God but is also desiring to please God with their living. They know that His way is best. So . . . we do our best and know that God will provide the rest. That's His promise. We hear this a great deal.
Times are indeed different . . .
In the beginning you laid the foundations of the earth, and the heavens are the work of your hands. Like clothing you will change them and they will be discarded. But you remain the same, and your years will never end. God does not change. The values in our society may change . . .
