There is a God and He is One

Selection from True Christian Religion ~ Emanuel Swedenborg

There is a universal influx from God into the souls of men of the truth that-
There is a God, and that He is one.

That there is an influx from God into man is evident from the universal confession that-

all good that is in itself good, and that exists in man and is done by him, is from God; in like manner every thing of charity and every thing of faith

for we read:

A man can take nothing except it be given him from heaven  (John 3:27);

and Jesus said:

Without Me ye are unable to do anything  (John 15:5);

that is, anything that pertains to charity and faith.

This influx is into the souls of men because the soul is the inmost and highest part of man, and the influx from God enters into that, and descends therefrom into the things that are below, and vivifies them in accordance with reception.

The truths that are to constitute belief flow in, it is true, through the hearing, and are thus implanted in the mind, that is, below the soul. But by means of such truths man is simply made ready to receive the influx from God through the soul — such as this preparation is, such is the reception, and such the transformation of natural faith into spiritual faith.

There is such an influx from God into the souls of men of the truth that God is one, because everything Divine, regarded most generally as well as most particularly, is God. And as the entire Divine coheres as one, it cannot fail to inspire in man the idea of One God; and this idea is strengthened daily as man is elevated by God into the light of heaven. For the angels in their light cannot force themselves to utter the word "gods." Even their speech closes at the end of every sentence in a oneness of cadence; and there is no other cause of this than the influx into their souls of the truth that God is One.

In spite of this influx into the souls of men of the truth that God is One, there are many who think that the Divinity of God is divided into several possessing the same essence; and the reason of this is that when the influx descends it falls into forms not correspondent, and influx is varied by the form that receives it, as takes place in all the subjects of the three kingdoms of nature. It is the same God who vivifies man and who vivifies every beast; but the recipient form is what causes the beast to be a beast and man to be a man. The same is true of man when he induces on his mind the form of a beast. There is the same influx from the sun into every kind of tree, but the influx differs in accordance with the form of each; that which flows into the vine is the same as that which flows into the thorn; but if a thorn were to be engrafted upon a vine the influx would be inverted and go forth in accordance with the form of the thorn.

For the earth which drinketh in the rain that cometh oft upon it, and bringeth forth herbs meet for them by whom it is dressed, receiveth blessing from God: But that which beareth thorns and briers is rejected, and is nigh unto cursing; whose end is to be burned.  Hebrews 6:7, 8

The same is true of the subjects of the mineral kingdom; the same light flows into limestone and into the diamond; but in the diamond it is transmitted, while in the limestone it is quenched.

In human minds these differences are in accordance with the forms of the mind, which become inwardly spiritual in accordance with faith in God, together with life from God, such forms being made translucent and angelic by a faith in one God, and on the contrary, made dark and bestial by a faith in more than one God, which differs but little from a faith in no God.
