Who or what are these "seven Spirits who are before His throne" and is
there a spiritual significance to why there are 7 spirits of God?

John to the seven churches which are in Asia: Grace [be] unto you, and
peace, from him which is, and which was, and which is to come; and from
the seven Spirits which are before his throne; And from Jesus Christ,
[who is] the faithful witness, [and] the first begotten of the dead, and
the prince of the kings of the earth. Unto him that loved us, and washed
us from our sins in his own blood, And hath made us kings and priests
unto God and his Father; to him [be] glory and dominion for ever and
ever. Amen. Revelation 1:4-6

This is what I have found:

Our curiosity is aroused. Did you ever get a greeting from a source you
did not know? It leaves you a little embarrassed. So this "grace" and
"peace" which is being sent to you from the "seven Spirits who are
before His throne" present an air of mystery. Let us hope that when we
are finished we may together have a clearer understanding. You may
actually know more about these "seven Spirits" then you thought you knew.

John saw Revelation 4 and 5 before he wrote chapter one. John injects
into chapter one what he could not have seen until chapter four. For
instance, it is in Revelation 4:5 that we are told about "seven lamps of
fire burning before the throne, which are the seven Spirits of God."
John recalls this vision and that these "seven Spirits of God" were
before the great throne. However, in this chapter the "seven Spirits"
were stationary. They were not sent forth and no greetings were mentioned.

John saw the vision of Revelation 5:6 in which he saw a "Lamb" with
"seven horns and with seven eyes, which are the seven Spirits of God
sent out into all the earth." The "seven Spirits" are now identified
with the Lamb. We have now been given three different descriptions of
these "seven Spirits of God." It is not until Revelation 5:6 that the
"seven Spirits" are SENT FORTH.

Revelation 4:5 speaks of the "seven Spirits" as "burning before the
throne," but they were not yet sent forth. They would not be and could
not be sent forth until the Lamb was found "worthy" to open the "seven
seals" and release the information contained therein. There is "but one
God, the Father, of whom are all things, and we in him: and one Lord
Jesus Christ, by whom are all things, and we by him." 1 Corinthians 8:6
As long as the Lamb had not been slain, the "seven Spirits of God" just
"burned before the throne" as "lamps" or "torches." They were a part of
God’s plan and purpose, but they were not sent forth. They were not
activated. So we see a stationary vision in Revelation 4, but in
Revelation 5 the Lamb is energized and through him the "seven Spirits of
God" are "sent out into all the earth," to gather His elect from the
"four winds of heaven and the four corners of earth."
