Whenever people begin to study the Scriptures without a prayerful, teachable spirit, they will twist the plainest passages away from their true meaning. The whole Bible should be given to the people just as it reads. LF 214.3
God gave the sure word of prophecy. Angels and even Christ Himself came to make known to Daniel and John the things that “must shortly take place” (Revelation 1:1). God did not reveal important matters about our salvation in a way to perplex and mislead the person who is honestly seeking for truth. The Word of God is plain to all who study it with a prayerful heart. LF 214.4
By the cry “Open-mindedness” people are blinded to Satan's deceptions. He succeeds in displacing the Bible with human speculations. People set aside the law of God, and the churches are in slavery to sin while they claim to be free. LF 214.5
God has permitted a flood of light to pour over the world in scientific discoveries. But, if the Word of God is not their guide, even the greatest minds become bewildered in trying to investigate how science and revelation fit together. LF 214.6
Human knowledge is partial and imperfect. This is why many are unable to harmonize their ideas of science with Scripture. Many accept things that are only theories as scientific facts, and they think that they should test God's Word by “what is falsely called knowledge” (1 Timothy 6:20). Because they cannot explain the Creator and His works by natural laws, they consider Bible history as unreliable. Those who doubt the Old and New Testaments too often go a step further and doubt the existence of God. Once they let go of their anchor, they beat about on the rocks of unbelief. LF 214.7
It is a masterpiece of Satan's deceptions to keep people speculating about things that God has not made known. Lucifer became dissatisfied because God did not share with him all the secrets of God's purposes, and he turned his back on the things God had revealed. Now he tries to fill people with the same spirit and lead them also to ignore the direct commands of God. LF 215.1
