(2) But there is a second result of the right life which ordinary observation and common sense may estimate. Wisdom is very uncompromising in her requirement of fair dealing between man and man. She cannot away with those commercial practices which can only be described as devising "evil against thy neighbour," who "dwelleth securely by thee."[40] Her main economic principle is this, that all legitimate trade is the mutual advantage of buyer and seller; where the seller is seeking to dupe the buyer, and the buyer is seeking to rob the seller, trade ceases, and the transaction is the mere inworking of the devil. Wisdom is quite aware that by these ways of the devil wealth may be accumulated; she is not blind to the fact that the overreaching spirit of greed has its rich and splendid reward; but she maintains none the less that "the curse of the Lord is in the house of the wicked; but He blesseth the habitation of the righteous."[41] It is a very impressive experience to enter the house of a great magnate whose wealth has been obtained by questionable means. The rooms are beautiful; works by the great masters shed their radiance of eternal truth from the walls; the library gleams with the well-bound books of moralists and religious teachers. The sons and daughters of the house are fair and elegant; the smile of prosperity is in every curtained and carpeted room, and seems to beam out of every illuminated window; and yet the sensitive spirit cannot be rid of the idea that "the curse of the Lord is in the house." On the other hand, the honourable man whose paths have been directed by the Lord, no matter whether he be wealthy or merely in receipt, as the result of a life's labour, of his "daily bread," has a blessing in his house. Men trust him and honour him.[42] His wealth flows as a fertilizing stream, or if it run dry, his friends, who love him for himself, make him feel that it was a good thing to lose it in order to find them. In proportion as the fierce struggle of competition has made the path of fair dealing more difficult, they who walk in it are the more honoured and loved. Nowhere does Wisdom smile more graciously or open her hand to bless more abundantly, than in the later years of a life which has in its earlier days been exposed, and has offered a successful resistance, to the strong temptations of unrighteous gain.
