2875. The good of life, or the affection of good, is insinuated by the Lord by an internal way, without man's knowing anything about it; but the truth of doctrine, or faith, by an external way, into the memory, whence it is called forth by the Lord in His own time and according to His own order, and is conjoined with the affection of good. This is done in man's freedom; for as before said, man's freedom is from affection. Such is the insemination and inrooting of faith. Whatever is done in freedom is conjoined, but that which is done under compulsion is not conjoined; as may be seen from considering that by no possibility can anything be conjoined except that by which we are affected: affection is the very thing that receives; to receive anything contrary to the affection is to receive it contrary to the life. Hence it is manifest that truth of doctrine, or faith, cannot be received except by the affection of it. But such as is the affection, such is the reception. It is only the affection of truth and good that receives the truth of faith; for they agree, and because they agree, they conjoin themselves together.
