Okay, I'll be bold and admit it: I never really have cared for that infamous song by John Lennon called "Imagine," especially due to the lines about imagining "no heaven" and "no religion," not to mention the completely God-less, humanistic message of the song.
However, here's a version that I rather enjoy. No, it's not by John Lennon, though it does use his tune. No, it doesn't tout the same anti-God, man-centered philosophy as the original, but it does give a message that we need to hear these days, especially on the heels of reports not long ago on the "cooked books" of global warming climatologists.
Perhaps it's best to remember that "The earth is the LORD's and the fullness thereof, the world and those who dwell therein." (Ps. 24:1) Somehow God has seen us through the scares of global cooling and nuclear holocaust; something tells me that He's still tending His creation and won't allow us puny human beings foolishly to destroy it.
