In one scale of the balance Jesus places all the world with its gold and gems, its art and science, its limitless values of woods and prairie soil--and in the other, a human soul. And then He says: Behold all this splendor! Look at it all, thou yearning child of man! It is not equal to the worth of your soul. Everything great and beautiful in life originates in the human soul. Through that, all noble thoughts and great ideas have come into being. Every work of art was formed in a human soul before it was painted upon the canvas, chiseled in marble, or written in a book. It is the stamp of the human soul that lends value to the work. Revere that _mark of the soul_ wherever you recognize it! But have reverence, above all, for the _soul_ itself. That has the worth of infinity. To "lose your soul" is to suffer everlasting damage which cannot be repaired or substituted by values of the world. The other thought is that about _exchange for your soul_. Wherever that precious soul is demanded of you, you can give nothing else in _exchange_. There is nothing in the whole, wide world that has value enough as exchange for a human soul. Neither is there anything whose value can equal that of the mark of your soul upon your work. If you owe your neighbor ten bushels of wheat, you may pay him back by giving him twenty bushels of corn or cash in exchange, and he will realize that he is paid in full. But this cannot be done where rests upon you the giving of your soul. This first of all you must consider in your relation to God who gave you your soul. He will demand it from you when your earthly life has ended. If your soul then is seen to have suffered corruption, it is not fit to enter into eternal life, and you have nothing else to give God in its place. It avails you nothing that you say: "O, Lord, I know that I have been so occupied with worldly things that I have not taken care of my soul, as I should have done. But, in this way I have made $10,000 which I now donate to missionary work."--My dear, that cannot compensate for the wrong that has been inflicted upon your soul. David understood this. Therefore he said to God: "For thou desirest not sacrifice; else would I give it: thou delightest not in burnt offering." But God delights in a prayer like this: "Have mercy upon me, O God, according to thy lovingkindness; according unto the multitude of thy tender mercies blot out my transgressions. Wash me thoroughly from mine iniquity, and cleanse me from my sin!" There is a human soul in this prayer--it is true that it is a suffering soul--but it is there. Thus God demands that your soul be in your _prayer_, your _praise_, and your _worship_, and there is nothing else that can take its place.
