There is an old tale about a man who spent all his days sitting by an old firehouse telling stories to the neighborhood children. The youngsters would flock around the man to hear him tell of bygone days. One striking feature of the old gentleman was that around each of his fingers he had tied a different colored string. The children would ask what the strings were for, and the old man would say that each one was to remind him of something important. This was the way he remembered things. But for everyone who came to him, he had this to share: "You don't need strings to remember the most important things. God gave us ten fingers and ten commandments, and if you keep one commandment on each finger, then you'll never forget any of them."
The commandments of God should be as much a part of us as the fingers which are part of our hands. If we take care to remind ourselves of the laws of God, then they will be forever inscribed on the very "table" of our heart.
"My son, keep my words, and lay up my commandments with thee.
Keep my commandments, and live; and my law as the apple of thine eye.
Bind them upon thy fingers, write them upon the table of thine heart."
