In the beginning was the Word, and God was the Word; by It were all things made that were made and by It the world was made (John 1:1, 3, 10). And in David:

By the Word of Jehovah were the heavens made (Ps. 33:6). In both of these passages "The Word" means the Divine truth. As the universe was created by this truth, so also was the universe preserved by it; for as subsistence is perpetual existence, so preservation is perpetual creation. [2] It was by means of Divine truth that man was made, because all things in man have relation to understanding and will, the understanding being the receptacle of Divine truth, and the will of Divine good; therefore, the human mind, which consists of those two principles, is nothing but a form of Divine good and Divine truth spiritually and naturally organized. The human brain is that form. And as the whole of man depends upon his mind, so all things of his body are appendages, which are moved by these two principles, and life from them. [3] From all this it can now be seen why God came into the world as the Word, and became Man, namely, that the work of redemption might be accomplished; for God then, by means of His Human, which was Divine truth, put on all power, overthrew the hells (which had grown up even as far as to the heavens where the angels were), and subjugated them, and reduced them to obedience to Himself, and this was done not by a spoken word but by the Divine Word which is Divine truth. Afterward He opened a great gulf between the hells and the heavens, which no one from hell can cross; if anyone attempts it, at the first step he is tortured like a serpent laid on a sheet of hot iron, or on an ant hill. For at the first approach of the odor of Divine truth the devils and satans instantly cast themselves into the abyss and throw themselves into caves and stop them up so closely that not a crevice is visible. This is because the will of such is in evils, and the understanding in falsities, that is, in what is opposite to the Divine good and the Divine truth. And because the whole of man, as just said, consists of these two principles of life, they are thus from head to foot, completely and grievously overpowered in consequence of their sensation of the opposite. [4] From all this it can be seen that the power of Divine truth is inexpressible. And as the Word which the Christian church possesses is the containant of Divine truth in three degrees, that Word is evidently what is meant in John (1:1, 3, 10). That its power is inexpressible I could prove by many evidences of experience in the spiritual world; but as these evidences would surpass belief, or appear incredible, I omit presenting them; but some you will find recorded above (n. 209). The following will serve to keep these truths in remembrance: That a church that is in Divine truths from the Lord has power over the hells, and that the Lord's words to Peter refer to such a church:

Upon this rock I will build my church, and the gates of hell shall not prevail against it (Matt. 16:18). This the Lord said after Peter had confessed, That He was the Christ, the Son of the living God (Matt. 16:16). "Rock" here means such truth, for everywhere in the Word "rock" means the Lord in respect to Divine truth.
