So we are mocked by this ...

So we are mocked by this world when we speak of God's coming judgment against all sin, and when we plead that sinners come to the Savior to avoid Hell. But we can't give up because our task is irksome, or because we are mocked. Neither can we live self-indulgent lives, because our convictions aren't based on some man-made and fallible calculations. They are based on the immutability of the Word of God.

Quotes from the same author

Darwin theorized that mankind (both male and female) evolved alongside each other over millions of years, both reproducing after their own kind before the ability to physically have sex evolved. They did this through "asexuality" ("without sexual desire or activity or lacking any apparent sex or sex organs"). Each of them split in half.

The Bible says that the earth is immovable. It cannot be moved. So now is your chance to prove your point. Run outside and move the earth. Perhaps you and your friends could jump on it, or find a rocky outcrop and push it together. Maybe after that little experiment you will concede that the earth is immovable.

Even Helen Keller, who was born blind and deaf, could see God. No doubt, in her silent darkness, every fragrant flower, every ray of the warm sun, every taste that touched her tongue told her that there was a God who created all things. Jodie Foster shouldn't therefore be surprised that people are surprised that she's an atheist.

We need to pray for our nation like never before, and then put legs to our prayers and preach the gospel to a sin-loving and Hell-bound world. To pray for America and at the same time ignore that command to preach the gospel to every creature, is nothing but empty hypocrisy. It is to honor God with our lips and have cold hearts that are far from Him. May He give us a love that moves us from the pews into the streets, and from our homes into our universities. God save us from the cozy comfort of lukewarm contemporary Christianity.

So, I'm not the only one who believes that there is such a thing as "the law of gravity," and if it's a law, it can be violated. If you hit the ground at 120 mph from 1,000 feet, you will suffer the consequences of violating what physics.about.com calls the law of gravity.
