4390. And built him a house. That this signifies the increase of good from truth in that state, is evident from the signification of "building a house," as being to instruct the external man in intelligence and wisdom (see n. 1488). And as intelligence belongs to truth, and wisdom to good, by "building a house" is here signified the increase of good from truth. (That a "house" denotes good may be seen above, n. 2233, 2234, 3128, 3142, 3652, 3720.) What the good of truth is, has been already stated (n. 4337, 4353), namely, that it is truth in will and act. This truth is what is called good, and the conscience which is from this good is called a conscience of truth. This good which is from truth increases in proportion as the man exercises charity from willing well, thus in proportion and in such a manner as he loves the neighbor.
 The reason why good and truth are mentioned so frequently in the explications, is that all things in heaven, and consequently all in the Lord's church, bear relation to good and truth. Speaking generally these two include all things that belong to doctrine and to life; truths, all things that belong to doctrine; and goods, all things that belong to life. Moreover, it is a universal fact that the human mind has no other objects than those which are of truth and good; its understanding, those which are of truth; and its will, those which are of good. Hence it is evident that truth and good are terms of the widest signification, and that their derivations are unutterable in number. This is the reason why truth and good are so often mentioned.
