Charles H. Spurgeon on Psalms 31:19

Oh how great is thy goodness, which thou hast laid up for them that fear thee. As a provident man will regulate his liberality towards all men in such a manner as not to defraud his children or family, nor impoverish his own house, by spending his substance prodigally on others; so God, in like manner, in exercising his beneficence to aliens from his family, knows well how to reserve for his own children that which belongs to them, as it were by hereditary right; that is to say, because of their adoption. John Calvin.
