Plenty of people have lived a long time, yet without accomplishing much. Methuselah lived for more than 900 years but that's just about all we know of him. There's got to be more to life than length. Alexander the Great conquered the whole world yet cursed himself because he never learned self-control. He subdued the world but defeated himself in the battle of life.
Real greatness is measured in terms of depth.
Everything about a building depends upon its foundation everything about a tree depends on its roots. The depth of a person tells the story. Shallow people are like a small brook they babble a lot but never say much. People with depth are like the sea the winds of circumstance may ruffle the surface, but underneath are great, quiet, untouched depths. The deep life the seasoned soul is not an accident.
