When at one time a brother came to me with the message that the world is flat, I was instructed to present the commission that Christ gave His disciples, “Go ye therefore, and teach all nations: ...and, lo, I am with you alway, even unto the end.” Matthew 28:19, 20. In regard to such subjects as the flat-world theory, God says to every soul, “What is that to thee? follow thou Me. I have given you your commission. Dwell upon the great testing truths for this time, not upon matters that have no bearing upon our work.” (GW 314.1) MC VC

Workers for God should not spend time speculating as to what conditions will prevail in the new earth. It is presumption to indulge in suppositions and theories regarding matters that the Lord has not revealed. He has made every provision for our happiness in the future life, and we are not to speculate regarding His plans for us. Neither are we to measure the conditions of the future life by the conditions of this life. (GW 314.2) MC VC

To my ministering brethren I would say, Preach the word. Do not bring to the foundation wood, hay, and stubble,—your own surmisings and speculations, which can benefit no one. Subjects of vital importance are revealed in the word of God, and these are worthy of our deepest thought. But we are not to search into matters on which God has been silent. (GW 314.3) MC VC

When questions arise upon which we are uncertain, let us ask, What saith the Scripture? And if the Scripture is silent upon the question at issue, let it not be made the subject of discussion. Let those who wish for something new, seek for that newness of life resulting from the new birth. Let them purify their souls by obeying the truth, and act in harmony with the instruction that Christ has given. (GW 314.4) MC VC
