After the visions are over Jesus says, "And behold, I am coming soon." (verse 7) and "Surely I am coming soon." (verse 20). He doesn't say the new heavens and earth are coming soon. In the preterist view, he did come soon after these visions to John-- he came in God's wrath visited upon Jerusalem and the temple in AD 70. In Matthew 16:28, 40 years (a generation) before this occurred, Jesus said to those around him, "Amen, I say to you, that there are men who are standing here who will not taste death until they will see The Son of Man who comes with his Kingdom.” This is exactly what happened. The Lord's coming against the Holy City ended the kingdom as it was manifested in the Old Covenant, and inaugurated the new kingdom of God.
Wow, we missed the Second Coming ...
The only difference between the preterist position, the JW position, the Seventh Day Adventist position is the year of Jesus supposed return.
Please describe this new Kingdom of Jesus’ that was inaugurated in 70AD. Where is it? What does it look like? What changed in 70AD that reflects the Kingdom of Jesus, the Lord of lords the King of kings?
