While there is need of thorough investigation of the Word of God, that precious truth may be discovered and brought to light, we should be guarded, that the spirit of controversy does not control in our discussions of the Sabbath-school lesson. In bringing out points upon which there may be a difference of opinion, the grace of Christ should be manifested by those who are seeking for an understanding of the Word of God. There should be liberty given for a frank investigation of truth, that each may know for himself what is the truth. Among the pupils of the Sabbath-school there should be a spirit of investigation, that those who are old enough to discern evidence may be encouraged to search for fresh rays of light, and to appreciate all that God may send to His people. The light which God will send to His people will never appear unless there is a diligent searching of the Word of truth. TSS 64.1
The world is full of all manner of error of a misleading nature, and it is essential that both pupils and teachers know that they know what is truth. There is need that we reverence the Word of God and recognize His voice in the living oracles, that we may practise its precepts and live by every word that proceedeth out of the mouth of God. Those that do the will of God shall know of the doctrine whether it be of God, for no deception will cloud their minds. God calls every one, both old and young, to make a diligent search in His Word, that they may discover the rich jewels of truth. Ministers and people, teachers and scholars, are all called to the work of studying the Bible. TSS 64.2
Precious light is to shine forth from the Word of God, and let no one presume to dictate what shall or what shall not be brought before the people in the messages of enlightenment that He shall send, and so quench the Spirit of God. Whatever may be his position of authority, no one has a right to shut away the light from the people. When a message comes in the name of the Lord to His people, no one may excuse himself from an investigation of its claims. No one can afford to stand back in an attitude of indifference and self-confidence, and say: “I know what is truth. I am satisfied with my position. I have set my stakes, and I will not be moved away from my position, whatever may come. I will not listen to the message of this messenger; for I know that it can not be truth.” It was from pursuing this very course that the popular churches were left in partial darkness, and that is why the messages of heaven have not reached them.
