Get thee behind me, Satan

You're smart. You're even exceptional. 

You are the finest generation this earth has ever seen. 

But that prophetic endorsement notwithstanding, you're not that smart. You are not resilient enough to tangle with the adversary. You can never match his cunning or his talent for deception and diversion. He will outsmart, outmaneuver, and outlast you every time you willingly consent to a duel. Lucifer is like the ultimate carnival barker: "Step right up. Come on in. Don't miss the greatest show on earth." But as soon as he has you inside his tent, he will leave you to twist in agony and isolation and darkness.

Gordon B. Hinckley

Very simply, our physical and spiritual safety lies in never even getting close to the line that separates light from dark, good from evil. Jesus Christ showed us how to deal with the adversary. When Satan tempted Him, there was no clever repartee, no battle of wills, just immediate dismissal "Get thee behind me, Satan. . . . Thou shalt not tempt the Lord thy God"  If the omniscient Jehovah wasn't willing to debate the adversary, how quickly ought we to run for our lives our eternal lives when confronted with even the slightest hint of evil.

"Satan would rather that you define yourself by your sins instead of your divine potential. 

Don't listen to Him." 

Dieter F. Uchtdorf
