Revelation 4:5-7 - These are the seven spirits

4:5,6a

We get more of the picture, with thunder and lightning, things often associated with the presence of the Lord. The seven lamps, representing the “seven spirits of God”, or the “sevenfold spirit” are John’s enigmatic way of referring to the Holy Spirit. Seven represents perfection and completeness. The glassy sea may be harking back to the temple, see 1 Kings 7:23. It is perhaps more likely that the sea represents God’s separateness. 

4:6b,7

The throne was surrounded by four living creatures. The description is very similar to that of the living creatures that Ezekiel saw (Ezek 1:5-11). The creatures represent the supreme beasts in various spheres. The lion is the king of the beasts, the ox is the most powerful, man is the pinnacle of God’s creation, and the eagle is the supreme being in the air.
