Taken from Patriarchs and Prophets by Ellen G. White, chapter 41, p. 459, 460

It was when the Israelites were in a condition of outward ease and security that they were led into sin. They failed to keep God ever before them, they neglected prayer and cherished a spirit of self-confidence. Ease and self-indulgence left the citadel of the soul unguarded, and debasing thoughts found entrance. It was the traitors within the walls that overthrew the strongholds of principle and betrayed Israel into the power of Satan. It is thus that Satan still seeks to compass the ruin of the soul. A long preparatory process, unknown to the world, goes on in the heart before the Christian commits open sin. The mind does not come down at once from purity and holiness to depravity, corruption, and crime. It takes time to degrade those formed in the image of God to the brutal or the satanic. By beholding we become changed. By the indulgence of impure thoughts man can so educate his mind that sin which he once loathed will become pleasant to him.
Satan is using every means to make crime and debasing vice popular. We cannot walk the streets of our cities without encountering flaring notices of crime presented in some novel, or to be acted at some theater. The mind is educated to familiarity with sin. The course pursued by the base and vile is kept before the people in the periodicals of the day, and everything that can excite passion is brought before them in exciting stories. They hear and read so much of debasing crime that the once tender conscience, which would have recoiled with horror from such scenes, becomes hardened, and they dwell upon these things with greedy interest.

Many of the amusements popular in the world today, even with those who claim to be Christians, tend to the same end as did those of the heathen. There are indeed few among them that Satan does not turn to account in destroying souls. Through the drama he has worked for ages to excite passion and glorify vice. The opera, with its fascinating display and bewildering music, the masquerade, the dance, the card table, Satan employs to break down the barriers of principle and open the door to sensual indulgence. In every gathering for pleasure where pride is fostered or appetite indulged, where one is led to forget God and lose sight of eternal interests, there Satan is binding his chains about the soul. “Keep thy heart with all diligence,” is the counsel of the wise man; “for out of it are the issues of life.” Proverbs 4:23. As man “thinketh in his heart, so is he.” Proverbs 23:7. The heart must be renewed by divine grace, or it will be in vain to seek for purity of life. He who attempts to build up a noble, virtuous character independent of the grace of Christ is building his house upon the shifting sand. In the fierce storms of temptation it will surely be overthrown. David’s prayer should be the petition of every soul: “Create in me a clean heart, O God; and renew a right spirit within me.” Psalm 51:10. And having become partakers of the heavenly gift, we are to go on unto perfection, being “kept by the power of God through faith.” 1 Peter 1:5.

Yet we have a work to do to resist temptation. Those who would not fall a prey to Satan’s devices must guard well the avenues of the soul; they must avoid reading, seeing, or hearing that which will suggest impure thoughts. The mind should not be left to wander at random upon every subject that the adversary of souls may suggest. “Girding up the loins of your mind,” says the apostle Peter, “Be sober, . . . not fashioning yourselves according to your former lusts in . . . your ignorance: but like as He which called you is holy, be ye yourselves also holy in all manner of living.” 1 Peter 1:13-15, R.V. Says Paul, “Whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.” Philippians 4:8. This will require earnest prayer and unceasing watchfulness. We must be aided by the abiding influence of the Holy Spirit, which will attract the mind upward, and habituate it to dwell on pure and holy things. And we must give diligent study to the word of God. “Wherewithal shall a young man cleanse his way? by taking heed thereto according to Thy word.” “Thy word,” says the psalmist, “have I hid in mine heart, that I might not sin against Thee.” Psalm 119:9, 11.

||Spirit of Prophecy is a term used to describe the writings of Ellen G. White. It is the “Testimony of Jesus Christ” (see Revelation 19:10), widely believed to have been uniquely manifested in the life and ministry of Ellen G. White (1827-1915).||
