It is from an unquestionable and commonly acknowledged truth, that Solomon here urgeth us to diligence in duty; and therefore to prove it would be but loss of time. As there are two worlds for man to live in, and so two lives for man to live, so each of these lives hath its peculiar employment. This is the life of preparation: the next is the life of rewards or punishments. We are now but in the womb of eternity, and must live hereafter in the open world. We are now but sent to school to learn the work that we must do for ever: this is the time of our apprenticeship; we are learning the trade that we must live upon in heaven.
