"principle of justice and honesty, will make you a man of influence. Now is the time to obtain a moral fitness for heaven. The church to which you belong must have the refining, elevating grace of Christ. God requires His followers to be men of good report, as well as to be pure, elevated, and honest; kind, as well as faithful. It is essential to be right in the weightier matters; but this is no excuse for negligence in things apparently of less importance. The principles of the law of God must be developed in the life and character. An amiable temper, combined with firm integrity and faithfulness, will constitute a moral fitness for any position. The apostle Peter exhorts: “Be courteous.” 4T 367.1"
"He hath shewed thee, O man, what is good; and what doth the Lord require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?"
Both passages emphasize justice, honesty, and moral fitness. While not a direct quote, the core principles align.
"We must be learners in the school of Christ. We cannot imitate His example unless we are pleasing in disposition and condescending in deportment. True Christian politeness should be cultivated. No one else can lessen our influence as we ourselves can lessen it through the indulgence of uncontrollable temper. A naturally petulant man does not know true happiness, and is seldom content. He is ever hoping to get into a more favorable position, or to so change his surroundings that he will have peace and rest of mind. His life seems to be burdened with heavy crosses and trials, when, had he controlled his temper and bridled his tongue, many of these annoyances might have been avoided. It is the “soft answer” which “turneth away wrath.” Revenge has never conquered a foe. A well-regulated temper exerts a good influence on all around; but “he that hath no rule over his own spirit is like a city that is broken down, and without walls.” 4T 367.2"
"Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls."
Both passages emphasize learning from Christ and cultivating a meek and gentle spirit. The EGW passage expands on the practical implications of this principle.
