In a special sense Seventh-day Adventists have been set in the world as watchmen and lightbearers. To them has been entrusted the last warning for a perishing world. On them is shining wonderful light from the word of God. They have been given a work of the most solemn import—the proclamation of the first, second, and third angels’ messages. There is no other work of so great importance. They are to allow nothing else to absorb their attention. 3TT 288.1
The most solemn truths ever entrusted to mortals have been given us to proclaim to the world. The proclamation of these truths is to be our work. The world is to be warned, and God's people are to be true to the trust committed to them. They are not to engage in speculation, neither are they to enter into business enterprises with unbelievers; for this would hinder them in their God-given work. 3TT 288.2
Christ says of His people: “Ye are the light of the world.” Matthew 5:14. It is not a small matter that the counsels and plans of God have been so clearly opened to us. It is a wonderful privilege to be able to understand the will of God as revealed in the sure word of prophecy. This places on us a heavy responsibility. God expects us to impart to others the knowledge that He has given us. It is His purpose that divine and human instrumentalities shall unite in the proclamation of the warning message. 3TT 288.3
