The Book of Revelation chapter 1:4-8
stresses the New Testament doctrines that:

Jesus is the Son of God;
He died and rose again; (vs. 5, 7 18)
Salvation is through His blood;
All true believers are priests; (vs. 6)
Jesus has power over death and hell; (vs. 18)
He is coming again in glory; (vs. 7)
All kindreds of the earth will wail because of Him.
