Arcana Coelestia # 3049
3049. 'And every good thing that was his master's was in his hand' means the goods and truths associated with those facts residing with the natural man. This is clear from the meaning of 'every good thing that was his master's' as both good and truth, for in itself truth is good since it springs from good - truth being the form that good takes, that is, when good receives a form so that it can be perceived in the understanding it is called truth; and from the meaning of 'the hand' as power, dealt with in 878. Thus the goods and truths residing with the natural man are meant here. General facts are not in themselves good, nor do they have any life; but the affection for them is what causes them to be good and to have life, for in that case they exist for the sake of their use. No one's affection is stirred by any fact or truth, except on account of the use it serves. The use is what makes it good, though the particular nature of the use determines the nature of the good.
Mercy
In regular language, "mercy" means being caring and compassionate toward people in poor states. That's a position we are all in relative to the Lord, all the time. Without Him we would be unable to choose what is good; without Him we would be unable to formulate a reasonable thought. Without Him, in fact, we would instantly cease to exist; we have life only because He constantly gives us life. So we are, quite literally, at His mercy. Fortunately, the Lord is caring and compassionate to a degree we cannot fathom. He is the source of all caring and all compassion, and of love itself. His mercy toward us never lessens, never abates, never ends; His whole purpose is to bring each of us, individually, to heaven. The meaning of "mercy" in the Bible is closely tied to this idea: it represents love in a general sense, and the desire for good that comes from love. It can also represent the desire for good and the ideas that describe it when those thoughts and desires are inspired by love of the Lord.
