DLW 282 - The Lord from eternity, who is Jehovah, created the universe and everything in it from Himself and not from nothing.

DLW 282
The Lord from eternity, who is Jehovah,
created the universe and everything in it from Himself and not from nothing.
People throughout the world know,
and every wise person from an interior perception acknowledges,
that there is one God who is the Creator of the universe.
People also know from the Word
that God, the Creator of the universe, is called Jehovah,
so named from the verb to be, because He alone just is.

Jehovah is called the Lord from eternity
because it was Jehovah who assumed a humanity
in order to save people from hell.
Moreover at that time He commanded His disciples to call Him Lord.
Consequently in the New Testament Jehovah is called the Lord,
as can be seen from considering the following statement.

[In the Old Testament:]
You shall love Jehovah your God with all your heart, and with all your soul...
(Deuteronomy 6:5)

And in the New Testament:
You shall love the Lord your God with all your heart, and with all your soul...
(Matthew 22:37)
