All things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets. Matthew 7:12.
The Saviour taught this principle [the golden rule] to make mankind happy, not unhappy; for in no other way can happiness come. God desires men and women to live the higher life. He gives them the boon of life, not to enable them merely to gain wealth, but to improve their higher powers by doing the work He has entrusted to mankind—the work of searching out and relieving the necessities of their fellow men. Man should not work for his own selfish interest, but for the interest of every one about him, blessing others by his influence and kindly deeds. This purpose of God is exemplified in Christ’s life.33Manuscript 132, 1902.
Seize every opportunity to contribute to the happiness of those around you, sharing with them your affection. Words of kindness, looks of sympathy, expression of appreciation, would to many a struggling, lonely one be as a cup of cold water to a thirsty soul. A word of cheer, an act of kindness, would go far to lighten the burdens that are resting heavily upon weary shoulders. It is in unselfish ministry that true happiness is found. And every word and deed of such service is recorded in the books of heaven as done to Christ…. Live in the sunshine of Christ’s love. Then your influence will bless the world.34The Youth’s Instructor, April 9, 1903.
