The first six verses of Psalm 110 are compared to its startling seventh, drawing out its Messianic and eschatological significance. The river flowing out of Eden already carries the living water later found fully in Christ.
The two special trees of Eden carry real significance, even as Eden itself remains inferior to the new heaven and earth to come. Both trees point past themselves to new creation, to God, and to man, with Christ transforming us to be like himself.
God breathes life into mere dust, and man’s move from wilderness to garden already pictures the move from earth to heaven. Even ‘the east’ points to Christ, a reminder that eschatology must be our first consideration in the history of salvation, not an afterthought.
Genesis grows more specific moving from chapter 1 into chapter 2, and Eden itself turns out to point toward the Paradise of Revelation 22. The real differences between the two get traced out, both of them finally about communion and fellowship with God.
