It frequently happens that the value of a thing lies in the fact that someone has possessed it. A very ordinary thing acquires a new value, if it has been possessed by some famous person. In any museum we will find quite ordinary things--clothes, a walking-stick, a pen, pieces of furniture--which are only of value because they were possessed and used by some great person. It is the ownership which gives them worth. It is so with the Christian. The Christian may be a very ordinary person, but he acquires a new value and dignity and greatness because he belongs to God. The greatness of the Christian lies in the fact that he is God's.
