All things both in heaven and in earth declare that the great law of life is a law of service. The infinite Father ministers to the life of every living thing. Christ came to the earth “as He that serveth.” Luke 22:27. The angels are “ministering spirits, sent forth to minister for them who shall be heirs of salvation.” Hebrews 1:14. The same law of service is written upon all things in nature. The birds of the air, the beasts of the field, the trees of the forest, the leaves, the grass, and the flowers, the sun in the heavens and the stars of light—all have their ministry. Lake and ocean, river and water spring—each takes to give. Ed 103.2
As each thing in nature ministers thus to the world's life, it also secures its own. “Give, and it shall be given unto you” (Luke 6:38), is the lesson written no less surely in nature than in the pages of Holy Writ. Ed 103.3
As the hillsides and the plains open a channel for the mountain stream to reach the sea, that which they give is repaid a hundredfold. The stream that goes singing on its way leaves behind its gift of beauty and fruitfulness. Through the fields, bare and brown under the summer's heat, a line of verdure marks the river's course; every noble tree, every bud, every blossom, a witness to the recompense God's grace decrees to all who become its channels to the world. Ed 103.4
