39. We can illustrate the fact that goodness loves what is true by taking priests, soldiers, merchants, and artisans as examples. With respect to priests, if they are focused on the good that a priest can do, which is looking out for the salvation of souls, teaching the way to heaven, and leading the people they teach, then because they are focused on this goodness, because they love and long for it, they acquire the truths that they teach and that enable them to lead.

On the other hand, priests who are not focused on the good that priests can do but rather on the gratifications of the office - and who are this way because of love for themselves and for the world, which is all they regard as good - then because of that love and longing they too acquire as much truth as the gratification that is their "goodness" inspires them to acquire.

As for soldiers, if they have a love for military service and see some good in it, whether in providing protection or in seeking their own glory, then because of the goodness they seek and in keeping with it they acquire the necessary knowledge and, if they are officers, understanding. These are the truths by which the pleasure of their love, which is their "goodness, " is nourished and given form.

As for merchants, if they commit themselves to being in business because they love it, they gladly take in everything that serves as a means of putting together and building what they love. These means, too, are like truths, when doing business is the goodness these people love.

As for artisans, if they apply themselves to their work diligently and love it as what makes their life worthwhile, they buy their tools and improve themselves by learning what they need to know. This is what makes their work good.

We can see from all this that truths are the means by which the good that we do out of love becomes manifest, becomes something; so goodness loves what is true in order to become manifest.

So in the Word, "doing the truth" means acting in such a way that some good will be done. This is the meaning of "doing the truth" in John 3:21, "doing what the Lord says" in Luke 6:46, "doing his commandments" in John 14:21, "doing his words" in Matthew 7:24, "doing the Word of God" in Luke 8:21, and "doing the statutes and judgments" in Leviticus 18:5.

This is also the meaning of "doing good" and "bearing fruit, " because what is done is something "good, " some "fruit."
