Bonhoeffer uses a similar phrase 'worldly Christianity'. It's J Gresham Machen that I want to line up most closely with. See his Christianity and culture here. Having done commentaries on Proverbs (Heavenly Wisdom) and Song of Songs (Heavenly Love), a matching title for Ecclesiastes would be Heavenly Worldliness. For my stance on worldliness, see 3 posts here.

Relative size of planets

Our Holiday Bible Club on creation set me thinking about the size of planets adn their relative distances.

Clyde W. Tombaugh, the discoverer of Pluto, had a famous model. For scale, the Earth's polar diameter of 7,900 miles is represented by one inch. So

The Sun is 9 feet in diameter.
Mercury is a pea 385 feet away.
Venus is a one-inch ball 700 feet away.
Earth is a one-inch ball 970 feet away.
Mars is a half inch marble 1,470 feet away (1/4 of a mile).
Jupiter is a ten-inch ball 5,030 feet away (approx. a mile).
Saturn is a nine-inch ball 1.67 miles away.
Uranus is a four-inch ball 3.5 miles away.
Neptune is a four-inch ball 5.5 miles away.
Pluto is a pea 7 miles away.
The total solar system fits within a circle 14 miles across.
