896. And Noah removed the covering of the ark and saw. That this signifies, on the removal of falsities the light of the truths of faith, which he acknowledged and in which he had faith, is evident from the signification of "removing the covering" as being to take away what obstructs the light. As by the "ark" is signified the man of the Ancient Church who was to be regenerated, by the "covering" nothing else can be signified than what obstructs or prevents from seeing heaven, or the light. What prevented was falsity; wherefore it is said that he "saw." In the Word "to see" signifies to understand and to have faith. Here it means that the man acknowledged truths and had faith in them. It is one thing to know truths, and quite another to acknowledge them, and still another to have faith in them. To know is the first thing of regeneration, to acknowledge is the second, to have faith is the third. What difference there is between knowing, acknowledging, and having faith is evident from the fact that the worst men may know, and yet not acknowledge, like the Jews and those who attempt to destroy doctrinal things by specious reasoning; and that unbelievers may acknowledge, and in certain states preach, confirm, and persuade with zeal; but none can have faith who are not believers.  Those who have faith, know, acknowledge, and believe, they have charity, and they have conscience; and therefore faith can never be predicated of anyone, that is, it cannot be said that he has faith, unless these things are true of him. This then it is to be regenerate. Merely to know what is of faith is of a man's memory, without the concurrence of his reason. To acknowledge what is of faith is a rational consent induced by certain causes and for the sake of certain ends. But to have faith is of conscience, that is, of the Lord working through conscience. This is abundantly evident from those who are in the other life. Those who only know are many of them in hell. Those who acknowledge are also many of them there, because their acknowledgment in the life of the body has been in certain states only, and when in the other life they perceive that what they had preached, taught, and persuaded others is true, they wonder greatly and acknowledge it only when it is recalled to their memory as what they had preached. But those who have had faith are all in heaven.
