"Chapter 12—The Knowledge of Health Principles We have come to a time when every member of the church should take hold of medical missionary work. The world is a lazar house filled with victims of both physical and spiritual disease. Everywhere people are perishing for lack of a knowledge of the truths that have been committed to us. The members of the church are in need of an awakening, that they may realize their responsibility to impart these truths. Those who have been enlightened by the truth are to be light bearers to the world. To hide our light at this time is to make a terrible mistake. The message to God's people today is: “Arise, shine; for thy light is come, and the glory of the Lord is risen upon thee.” 7T 62"
"Ye are the light of the world. A city that is set on an hill cannot be hid."
EGW directly quotes Isaiah 60:1, "Arise, shine; for thy light is come, and the glory of the Lord is risen upon thee," and connects it to the church's responsibility to share truth.
"On every hand we see those who have had much light and knowledge deliberately choosing evil in the place of good. Making no attempt to reform, they are growing worse and worse. But the people of God are not to walk in darkness. They are to walk in the light, for they are reformers. 7T 62.2"
"For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:"
Both passages contrast walking in darkness with walking in the light, emphasizing the transformative power of faith and the call to live righteously.
"Before the true reformer, the medical missionary work will open many doors. No one need wait until called to some distant field before beginning to help others. Wherever you are, you can begin at once. Opportunities are within the reach of everyone. Take up the work for which you are held responsible, the work that should be done in your home and in your neighborhood. Wait not for others to urge you to action. In the fear of God go forward without delay, bearing in mind your individual responsibility to Him who gave His life for you. Act as if you heard Christ calling upon you personally to do your utmost in His service. Look not to see who else is ready. If you are truly consecrated, God will, through your instrumentality, bring into the truth others whom He can use as channels to convey light to many that are groping in darkness. 7T 62.3"
"Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen."
EGW's emphasis on individual responsibility, immediate action, and spreading the message aligns with the Great Commission in Matthew 28:19-20, which calls believers to go and make disciples.
