It is God's purpose to manifest through His people the principles of His kingdom. That in life and character they may reveal these principles, He desires to separate them from the customs, habits, and practices of the world. He seeks to bring them nearer to Himself, that He may make known to them His will. His purpose for His people today is the same that He had for Israel when He brought them forth from Egypt. By beholding the goodness, the mercy, the justice, and the love of God revealed in His church, the world is to have a representation of His character. And when the law of God is thus exemplified in the life, even the world will recognize the superiority of those who love and fear and serve God above every other people in the world. CT 321.1
Seventh-day Adventists, above all people, should be patterns of piety, holy in heart and in conversation. To them have been entrusted the most solemn truths ever committed to mortals. Every endowment of grace and power and efficiency has been liberally provided. They look for the near return of Christ in the clouds of heaven. For them to give to the world the impression that their faith is not a dominating power in their lives is greatly to dishonor God. CT 321.2
Because of the increasing power of Satan's temptations, the times in which we live are full of peril for the children of God, and we need to learn constantly of the Great Teacher, that we may take every step in surety and righteousness. Wonderful scenes are opening before us; and at this time a living testimony is to be borne in the lives of God's professed people, so that the world may see that in this age, when evil reigns on every side, there is yet a people who are laying aside their will and are seeking to do God's will—a people in whose hearts and lives God's law is written.
