To build something generally means to put together a variety of simpler pieces to make a useful and more complex structure, as to build a house out of wood or bricks, and it is commonly used this way in the Word. In the land of Shinar men wished to build a tower, and in the new testament Jesus advised that a wise man should build his house on a rock. But in a representative sense the meaning is to build a mental and spiritual structure, like the doctrine of a church or the individual concepts of spiritual reality in a single mind. The building materials are representative also. The tower of Babel was built of brick, which is man-made rock, or representatively, man-made "truths", that is"truths" not from God but ideas of spiritual reality thought out by men. The house that the wise man would build was founded on a natural or "God-made" rock, which means a truth from the Word.

1017. That the nature of the multiplying depends on the character of the affection, let the person serve as an example who accepts the basic assumption that faith alone saves somebody even when he does not perform any charitable action, that is, has no charity, and so separates faith from charity. Such a person separates faith from charity not only because he has accepted that assumption since earliest childhood, but also because he really does think that if anyone were to say that charity, or the works of charity, were the essential constituent of faith and led a devout life on those grounds he would inevitably be placing merit in works, which however is a falsity. Thus he rejects charity and considers the works of charity to be worthless, and so keeps solely to the idea of faith, which is no faith at all when devoid of its essential, which is charity. As long as he confirms himself in that assumption he in no way acts from an affection for good but from the affection inherent in the delight of being able to live without any restriction on his evil desires. And anyone among those like this who relies on many different facts to confirm that assumption does not act from an affection for truth but from glory of self, in order that he may consequently appear greater, more learned, and more eminent than everybody else, and so be promoted to the ranks of the distinguished and wealthy. Thus he acts from the delight accompanying the affection, and this delight causes things of a confirmatory nature to multiply, for as stated, the character of the affection determines that of the multiplication. In general, if a basic assumption is false, nothing but falsities can possibly result from it. In fact everything conforms to the basic assumption. Indeed, as I know from experience, which in the Lord's Divine mercy I will describe elsewhere, people who confirm themselves in such basic assumptions concerning faith alone and who have not been governed at all by charity, pay no attention to, and so to speak do not see, all that the Lord has said so many times about love and charity, as in Matthew 3:8-9; 5:7, 43-48; 6:12, 15; 7:1-20; 9:13; 12:33; 13:8, 27; 18:21- end; 19:19; 22:35-39; 24:12-13; 25:34, 40, 41, 45; Mark 4:18-20; 11:13-14, 20; 12:28-34; Luke 3:8-9; 6:27-38, 43-end; 7:47; 8:8, 14-15; 10:25-28; 12:58-59; 13:6-9; John 3:19, 21; 5:42; 13:34-35; 14:15, 21, 23; 15:1-17; 21:15-17.
