They each contain a declaration from Jesus that He is coming soon, quickly!

Here they are in NASB:

Revelation 3:11 – "I am coming quickly; hold firmly to what you have, so that no one will take your crown."

Revelation 22:7 – "And behold, I am coming quickly. Blessed is the one who keeps the words of the prophecy of this book."

Revelation 22:12 – "Behold, I am coming quickly, and My reward is with Me, to reward each one as his work deserves."

Revelation 22:20 – "He who testifies to these things says, 'Yes, I am coming quickly.' Amen. Come, Lord Jesus."

Common Thread:

All four emphasize the nearness of Christ's coming.

The Greek word used for "quickly" is "tachu" (ταχύ), meaning swiftly, without delay, not "eventually" or "after a long time".

This repeated emphasis reinforces the urgency and imminence of the events described in Revelation, making audience relevance critical, Jesus was speaking to them, not to a distant future generation.

From a Preterist perspective, this supports the fulfilled view that Christ's coming in judgment was imminent and fulfilled in the first century, particularly at the destruction of Jerusalem in 70 AD.

Again, This theme of urgency is repeated multiple times to affirm that His coming was near to the original audience, supporting the fulfilled view that these events took place in the first century.
