Think that the man in the next house has the same amount of sin in him, and all the people in your street are like that. Multiply that by the number of all the streets in your city, and that by the number of cities in your country, and that by the number of countries in the world, and you have a ghastly spectre under which your imagination staggers. By forgiving the sin of the world, and by taking it away, through you and me and other subjects of His kingdom. Christians, the followers of Christ, He said, are the salt of the earth, and it is that salt that takes away the rottenness of the world. He takes away the guilt and the power of it, and you help Him to remove it by being salt in the society in which you live.
Salt is that which keeps society from becoming rotten.
Christianity is the great antiseptic of society. If you were to take Christianity out of New York, Chicago, Berlin, or Paris, those cities, in a few generations, would go to pieces, even physically, and be swept off the earth. Now, we are to be the salt of Chicago, New York and the great cities of the world. The work of salt is to prevent this, as well as to cure it. Keep those children pure to the end of their lives.
