SHOULD WE EXAMINE OUR BIBLE BELIEFS?
YES - Millions now living will Never Die (1920) page 13
Every man should be persuaded in his own mind and no man should permit himself to be deterred from examining a question based upon the Bible because a clergyman or anyone else makes the unsupported assertion that it is dangerous or unworthy of consideration. Error always seeks the dark, while truth is always enhanced by the light. Error never desires to be investigated.
YES - Watchtower, May 1, 1958 p.261; Is Your Religion the Right One?
It is important...that you "keep testing whether you are in the faith," as Paul declared. Keep checking to see whether the things you believe are in keeping with God's Word. But the question is, Are you willing to put your religion through such a test? There is nothing to fear, because if you have the right religion you can only be reassured by the examination. And if what you believe is not in keeping with the Bible, then you should welcome the truth, because it leads to light and life.
YES - w64 4/1 p. 195 - "How can you put your religion to the test? By using the Bible as your measuring rod. That is the rule beside which you can put the doctrines and practices of your religion to see if they measure up to God’s standards. Extremely helpful, too, is the discussing of Bible doctrine and religious practice with those who have made a serious study of the Bible—Jehovah’s witnesses."
YES - w89 1/15 p. 6 Are You Open to New Ideas?
Rather than blindly accepting every new idea presented to us, we need to do careful and exact research, just as a judge would in hearing a legal case.
YES - w91 4/8 p. 23 -"Test your beliefs against God’s Word. Honest self-examination, comparing your beliefs with the Scriptures, will help you determine if your faith will pass the all-important test of God’s approval."
YES - w01 4/15 p. 21 -"Thus, true Christians do not need to look to any human as the source of inspired revelation. They are careful not to ‘make the word of God invalid’ because of human tradition."
YES - w02 4/1 p. 3 Should Faith Be Based on Reason?
Does it not strike you as odd that the person who does extensive research just to buy a car—which one day will end up on the scrap heap—would say regarding his religion, ‘If it was good enough for my parents, it’s good enough for me’?
YES - Watchtower, February 1, 2003, p.32
Certain first-century Jews might sincerely have believed in their way of worshiping God, but their zeal was “not according to accurate knowledge.” (Romans 10:2) For us to be acceptable to God, our sincere beliefs must be based on accurate information.
NO - km 9/07 p.3 -"Does "the faithful and discreet slave" endorse independent groups of Witnesses who meet together to engage in Scriptural research or debate?"—Matt. 24:45, 47. -"No, it does not."
