ANSWER: Notice what God inspired to be written in - Revelation 5:6 "And I looked, and behold, in the midst of the throne and of the four living creatures, and in the midst of the elders, stood a Lamb as though it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent out into all the earth."
This verse describes these Spirits as being the "seven eyes" of the "Lamb." They are seven angelic beings who serve as the seven observers for Jesus Christ. In Revelation 1:4 we find that these seven angels have access to the very throne of God in heaven. Notice: "John, to the seven churches which are in Asia: Grace to you and peace from Him who is and who was and who is to come, and from the seven Spirits who are before His throne."
The function of these seven angels is described in II Chronicles 16:9 "For the eyes of the LORD run to and fro throughout the whole earth, to show Himself strong on behalf of those whose heart is loyal to Him..." This description of the seven Spirits is repeated in Zechariah 4:10 "For who has despised the day of small things: For these seven rejoice to see the plumb line in the hand of Zerubbabel. They are the eyes of the LORD, which scan to and fro throughout the whole earth."
These seven angels have a specific and important responsibility. They continually go throughout the entire earth to observe conditions and report them to Jesus Christ in heaven.
