AE 701c - covenants, old & new

AE 701c [12]
. . . the covenants that the Lord makes with men
must be on the part of the Lord and on the part of men;
they must be on the part of both that there may be conjunction . . .

[15-16]
. . . "the old covenant," . . . was a conjunction through such Divine truth
as is contained in the books of Moses
and is called "commandments, judgments, and statutes,"
in which . . . there lay inwardly hidden
such Divine truth as is in heaven, which is internal and spiritual.

This Divine truth was disclosed by the Lord when He was in the world;
and as through this alone there is conjunction of the Lord with men,
therefore this is what is meant by "the new covenant,"
also by "His blood," which is therefore called "the blood of the new covenant."
"Wine" has a similar meaning.
