Manhattan, New York, pastor Tim Keller once said that in 1970 a Sunday school teacher changed his life with a simple illustration.

The teacher said, "Let's assume the distance between the earth and the sun (92 million miles) was reduced to the thickness of this sheet of paper. If that is the case, then the distance between the earth and the nearest star would be a stack of papers 70 feet high. And the diameter of the galaxy would be a stack of papers 310 miles high."

Then Keller's teacher added, "The galaxy is just a speck of dust in the universe, yet Jesus holds the universe together by the word of his power."

Finally, the teacher asked her students, "Now, is this the kind of person you ask into your life to be your assistant?"
