On the back of a door in the farmhouse where I grew up were some pencil marks measuring the height of my sister, my brother, and myself at different ages. It was our parents' custom to check these marks from time to time and note how much we had grown.
Far more important than material growth, of course, is spiritual growth. How can it be measured? Not in inches or meters, but there are reliable waymarks of progress, and one who is alert to note these is not as apt to stand still spiritually or drift backward.
One good indicator of spiritual progress is self-improvement, or regeneration. Another is increased interest in the study of Christian Science and in church activity— a deepened sense of dedication. Still another, perhaps the most important and the outcome of the first two, is inspiration resulting in healing or "signs following"—the clear demonstration of this Science in our lives.
