What does Revelation 1:5 mean?

And from Jesus Christ—the trustworthy witness, the first to rise from the dead, and the ruler over all the kings on earth. He loves us and freed us from our sins by his own blood. Revelation 1:5 - Modern Text Bible

(Jesus is described as the ultimate witness, the first to conquer death, and the true authority over every ruler. His love and sacrifice are what set us free.)
