SD 4781 - why the Lord was born on this earth

SD 4781
There was a talk concerning the Lord,
why He was born in this earth and not in some other;
and [it was seen] that the reason was,
because, in this earth,
doctrine communicated from heaven,
could be propagated throughout the whole world,
and remain for thousands of years;
for, in this earth, from ancient times,
such things have been committed to writings,
and, afterward, to types,
and these can be spread throughout the whole world,
and also remain;
for such communications and travellings exist in this earth,
and not elsewhere . . ..
Besides, also,
when the heavenly doctrine concerning the Lord
is known in one earth,
the rest are thus able to know it,
when they become spirits and angels.
