Revelation 1:4–8 identifies John’s audience as the seven churches in Asia. John addresses these churches with a greeting from the triune God, and he ascribes praise to Jesus. Jesus is coming in glory, John declares, and His coming will be visible to everyone. At that time, the tribes of Israel will express remorse because of His crucifixion. John concludes this passage by quoting Jesus as saying He is the beginning, the eternal Almighty One.
