And I saw another angel ascending from the rising of the sun, having the seal of the living God; and he cried out with a loud voice to the four angels to whom it was granted to harm the earth and the sea, saying, "Do not harm the earth or the sea or the trees until we have sealed the bond-servants of our God on their foreheads."
The earth is the LORD's, and all it contains,
The world, and those who dwell in it.
For He has founded it upon the seas
And established it upon the rivers.
"Blessed are the poor in spirit, for theirs is the kingdom of heaven."
The various Bible readings today echo nicely. The message in Relevation and Psalms is loud and clear. We who have the ability to "harm the earth or the sea or the trees" should not do so, for "the earth is the Lord's, and all it contains". We do not own the world. We are here to manage it. But what a lousy manager we have been to have let the earth and the sea and the trees be harmed to such an extent as we see today, all because we greedily wish to have more and more. And so Jesus urges us to become "the poor in spirit", for it is by becoming thus that we inherit the kingdom of heaven.
