Do you know your value?

"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." -- William Barclay
