Isaiah 6:1-3 (NIV)
1 In the year that King Uzziah died, I saw the Lord, high and exalted, seated on a throne; and the train of his robe filled the temple.
2 Above him were seraphim, each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying.
3 And they were calling to one another: “Holy, holy, holy is the Lord Almighty; the whole earth is full of his glory.”

Like heaven we are to speak, and think, in alignment with a reality that will be but is not yet.

Revelation 5:13-14 (NIV)
13 Then I heard every creature in heaven and on earth and under the earth and on the sea, and all that is in them, saying: “To him who sits on the throne and to the Lamb be praise and honor and glory and power, for ever and ever!”
14 The four living creatures said, “Amen,” and the elders fell down and worshiped.

There will be a great global all creatures worship service - guaranteed.

John 11:26 (NIV)
26 and whoever lives by believing in me will never die. Do you believe this?”

Jesus talks like “death is no more” because in Him it is.

This talking now like the future is already the reality should calibrate how we talk.

This negates manipulative fear motivation techniques like:
  “If this situation doesn’t change we will never make it.”
  “If the White House doesn’t change America will end.”
  “If the Muslims get control this planet is doomed.”

We speak differently because we are in Christ and a Kingdom that are filling the NOW with the FUTURE.
