For to be carnally minded is death; but to be spiritually minded is life and peace. Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be. Romans 8:6, 7. HP 160.1
The natural mind leans toward pleasure and self-gratification. It is Satan's policy to manufacture an abundance of this. He seeks to fill the minds of men with a desire for worldly amusement, that they may have no time to ask themselves the question, How is it with my soul? The love of pleasure is infectious. Given up to this, the mind hurries from one point to another, ever seeking for some amusement. Obedience to the law of God counteracts this inclination and builds barriers against ungodliness....

The ability to enjoy the riches of glory will be developed in proportion to the desire we have for these riches. How shall an appreciation of God and heavenly things be developed unless it is in this life? If the claims and cares of the world are allowed to engross all our time and attention, our spiritual powers weaken and die for lack of exercise. In a mind wholly given up to earthly things every inlet through which light from heaven may enter is closed. God's transforming grace cannot be felt on mind or character.2The Review and Herald, May 28, 1901. HP 160.3
We are living amid the perils of the last days, and we should guard every avenue by which Satan can approach us with his temptation.... A mere assent to the truth will never save a soul from death. We must be sanctified through the truth; every defect of character must be overcome, or it will overcome us and become a controlling power for evil. Commence without a moment's delay to root out every pernicious weed from the garden of the heart; and through the grace of Christ allow no plants to flourish there but such as will bear fruit unto eternal life. HP 160.4
Cultivate whatever in your character is in harmony with the character of Christ. Cherish those things that are true, honest, just, pure, lovely and of good report; but put away whatever is unlike our Redeemer.... Every soul that gains eternal life must be like Christ, “holy, harmless, undefiled, separate from sinners” (Hebrews 7:26).3The Review and Herald, June 3, 1884. HP 160.5
