10506. 'And Jehovah said, The one who has sinned against Me, I will blot him out of My book' means the reply, that they will be destroyed who turn themselves away from the Divine. This is clear from the meaning of 'Jehovah said to Moses' as the reply; from the meaning of 'sinning against Jehovah' as turning themselves away from the Divine, dealt with above in 10498; and from the meaning of 'being blotted out of Jehovah's book' as not appearing in heaven, thus the destruction of spiritual life. The reason why 'being blotted out of Jehovah's book' has this meaning is that those whose interest lies in external things separated from what is internal cannot receive anything from heaven, since the internal is what receives anything from there, and the only source from which the external without the internal receives something is hell.
Heaven resides with a person in his internal; the internal is his 'book of life'; and the things within his internal are derived from heaven and exist from the Lord, see immediately above in 10505.
