'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

15. Throughout heaven they do not know any other Father than the Lord, for They are one, as He Himself has said,

I am the way, the truth, and the life. Philip said, Show us the Father. Jesus said to him, Have I been with you so long, and yet you do not know Me, Philip? He who has seen Me has seen the Father. So why do you say, Show us the Father? Do you not believe that I am in the Father and the Father in Me? Believe Me that I am in the Father and the Father in Me. John 14:6, 8-11.
