The healthy body is being constantly renewed. This is just as true mentally and spiritually. There is so much in God’s Word about renewal of life that it is strange that any conscientious Christian would be afraid of change in his outlook on life or even in his religious ideas. Of course, the fear is that change would mean loss of faith, but this is never true if the faith is in the living God and not in one’s ideas of God. God never changes, but our minds must be open to new knowledge or grow stagnant. When we quit growing we begin to die. Renewal can come to anyone at any time by turning to God in faith.
