Criminal investigators hoping to develop suspects in difficult cases have been asking Google to reveal who searched for specific information online, seeking “reverse keyword” warrants that critics warn threaten the privacy of innocent people.

Unlike traditional search warrants that target a known suspect or location, keyword warrants work backward by identifying internet addresses where searches were made in a certain window of time for particular terms, such as a street address where a crime occurred or a phrase like “pipe bomb.”

Police have used the method to investigate a series of bombings in Texas, the assassination of a Brazilian politician and a fatal arson in Colorado.

Every time we turn on the lights, use electric heat or most appliances, a stream of alternating current (AC) supplies the power. Much of modern life depends on scientist and inventor Nikola Tesla’s harnessing the phenomena in the 1880s. In 1934, he stated that deep thought was the key to this level of ingenuity: “Originality thrives in seclusion, free of outside influences beating upon us to cripple the creative mind. Be alone, that is the secret of invention; be alone, that is when ideas are born.”

I cited this in a recent sermon, touching briefly on the subject of correct meditation—something completely misunderstood in a world of smartphones, computers, television and other devices vying for our attention. Everything around you originated with thought. So did we. Genesis 1:26 reads, “And God said, Let Us make man in our image, after Our likeness…” God determined to do something—after careful thought!—and created mankind. He is a Being capable of unfathomably deep thought, yet He created us to be like Him. He expects us to think, too.

Of course, this includes right thought about right things. Simply “emptying the mind” as most proponents of meditation advocate, invites disaster. Notice what Christ explained about this very subject in Luke 11:24-26: “When the unclean spirit is gone out of a man, he walks through dry places, seeking rest; and finding none, he says, I will return unto my house whence I came out. And when he comes, he finds it swept and garnished. Then goes he, and takes to him seven other spirits more wicked than himself; and they enter in, and dwell there: and the last state of that man is worse than the first.”
