People may not grow up . . . The hair gets thinner, the midsection gets fuller, the memory loses it's sharpness and our health places limits on even the most carefree. We are changing all the time. We change our clothes, we change our minds, we change directions, we change jobs, we change cars, and we change moods in an instant. Since change is a part of our lives it is hard for us to grasp the truth that God does not change.
Human beings have their good days and bad days.
This characteristic of God is called His immutability. It forms the basis for the English words mutation and mutant . A mutant is a creature who has undergone an abnormal change in its appearance. Thus he is immutable. He lives forever without mutation, alteration, variation, or fluctuation.
