Growth and change take time, but one of the wonderful things is that the person does not know how growth takes place. The Lord Christ spoke about the changes that happen in the life of a person, and mentioned the following parable. “The kingdom of God is as if a man should scatter seed on the ground, and should sleep by night and rise by day, and the seed should sprout and grow, he himself does not know how. For the earth yields crops by itself: first the blade, then the head, after that the full grain in the head.” (Mark 4:26-28) The statement “he himself does not know how,” means that when a person places himself under grace, and with divine truth, he will grow and change, yet he himself does not know how; but he has to begin now.
