(3) Further, Wisdom commands not only justice, but generosity. She requires her children to yield the first-fruits of all their possessions to the Lord, and to look tenderly upon His poor. "Withhold not good from them to whom it is due, when it is in the power of thine hand to do it. Say not unto thy neighbour, Go, and come again, and to-morrow I will give; when thou hast it by thee."[43] And the teaching of experience is that those who act upon this precept purchase to themselves a good possession. The main value of the Mammon of unrighteousness is, as our Lord says, to make to ourselves friends with it, friends who shall receive us into the everlasting habitations. The money we spend upon our own pleasures, and to promote our own interests, is spent and gone; but the money given with an open hand to those poor children of God, to whom it is strictly due, is not spent at all, but laid up in the most secure of banks. There is no source of joy in this present world to be compared with the loving gratitude of the poor whom you have lovingly helped. Strangely enough, men will spend much to obtain a title which carries no honour with it, forgetting that the same money given to the needy and the suffering purchases the true honour, which gives the noblest title. For we are none of us so stupid as to think that the empty admiration of the crowd is so rich in blessing as the heartfelt love of the few. But in enumerating these external results of right living we have only touched incidentally upon the deeper truths which lie at the root of it. It is time to look at these.
