The design of the earth

The Earth . . . its size is perfect. The Earth's size and corresponding gravity holds a thin layer of mostly nitrogen and oxygen gases over the surface of the earth. Only extending about 50 miles above the Earth's surface, our atmosphere contains the right mixture of gases to sustain life. If Earth were smaller, an atmosphere would be impossible, like the planet Mercury. If Earth were larger, its atmosphere would contain free hydrogen, like Jupiter.(4) Earth is the only known planet equipped with an atmosphere appropriate for plant, animal and human life.

The Earth is located exactly the right distance from the sun. Consider the temperature swings we encounter, roughly -30 degrees to +120 degrees. If the Earth were any further away from the sun, we would all freeze. Any closer and we would burn up. Even a fractional variance in the earth's position to the sun and life on Earth would be impossible. The Earth remains at its perfect distance from the sun while it rotates around the sun at a speed of nearly 67,000 mph. And the Earth's rotation on its axis allows the entire surface of the earth to be properly warmed and cooled every day.

Our moon is the right size and distance from the Earth. The moon creates important ocean tides and movement so ocean water does not stagnate, and yet it restrains our massive oceans from spilling over across the continents.(5)

Commitment - Simple as That - Will make a long lasting marriage

During a potluck dinner at my church a few years back, the pastor announced that a couple in attendance had recently celebrated their 50th wedding anniversary. Later in the evening, word got around that this elderly couple needed a ride back to their home, which was about 30 minutes away. My wife and I immediately volunteered.

As newlyweds, we were eager to have a conversation with these matrimonial gladiators.As we approached their home, I asked, "So what do you two feel is the secret to a successful marriage?"

"Commitment," they said, both speaking at the same time. "So many people feel like their marriage is failing because they're not happy all the time," the wife continued. "You're never going to be happy all the time. But you can stay committed."

I have to admit, I was a little disappointed by her answer. I was hoping for something like, "Start playing golf together" or "Eat dinner as a family every night." I guess I was hoping for something more concrete—more practical. Yet, as my wife and I celebrate our 3rd anniversary, I've been struck over and over again by the wisdom of her words.
