4 It is then a secret of gainful dealing I am giving; learn so to trade. For you commend the merchant who sells lead and gets gold, and will you not commend the merchant, who lays out money, and gets righteousness? But you will say, I do not lay out my money, because I have not righteousness. Let him who has righteousness lay his money out; I have not righteousness, so at least let me have my money. Do you not then wish to lay out your money, because you have not righteousness? Yea, lay it out then rather that you may have righteousness. For from whence shall you have righteousness but from God, the Fountain of righteousness? Therefore, if you will have righteousness, be God's beggar, who just now out of the Gospel urged you to ask, and seek, and knock. He knew His beggar, and lo the Householder, the mighty rich One, rich, to wit, in riches spiritual and eternal, exhorts you and says, “Ask, seek, knock; he that asks receives, he that seeks finds, to him that knocks it shall be opened.” He exhorts you to ask, and will he refuse you what you ask?
