You . . . have redeemed us to God by Your blood out of every tribe and tongue and people and nation.
Revelation 5:9

“Immigration” is presently the hottest geo-political word in the world. America is trying to solve the question of undocumented aliens entering without legal permission. And Europe is wrestling with additional millions who are fleeing persecution and war in their Middle Eastern homelands.

Recommended Reading: Colossians 1:9-29

“Birds of a feather flock together” is a truism for a reason. Human beings prefer the comfort of familiarity to the discomfort of changing surroundings—including new languages, customs, and religions. But in heaven, God’s original vision for humanity will be restored. Humanity will be unified, on the basis of faith in Christ, as a physical body that manifests the spiritual body we are on earth. Christians will be redeemed “out of every tribe and tongue and people and nation” on earth. That doesn’t mean our “tribes” and “tongues” will be preserved in heaven. It does mean that the fears we have now of “others” will be erased as we are united in love for eternity.

Better to live now as we will live in heaven—immigrants united as one in Christ.

You must therefore live, in the present, as far as possible like you will live in the future.
