There are mysteries in the plan of redemption—the humiliation of the Son of God, that He might be found in fashion as a man, the wonderful love and condescension of the Father in yielding up His Son—that are to the heavenly angels subjects of continual amazement. The apostle Peter, speaking of the revelations given to the prophets of “the sufferings of Christ, and the glory that should follow,” says that these are things which “the angels desire to look into.” And these will be the study of the redeemed through eternal ages. As they contemplate the work of God in creation and redemption, new truth will continually unfold to the wondering and delighted mind. As they learn more and more of the wisdom, the love, and the power of God, their minds will be constantly expanding, and their joy will continually increase. 2TT 307.1
If it were possible for created beings to attain to a full understanding of God and His works, then, having reached this point, there would be for them no further discovery of truth, no growth in knowledge, no further development of mind or heart. God would no longer be supreme; and men, having reached the limit of knowledge and attainment, would cease to advance. Let us thank God that it is not so. God is infinite; in Him are “all the treasures of wisdom and knowledge.” And to all eternity men may be ever searching, ever learning, and yet they can never exhaust the treasures of His wisdom, His goodness, and His power. 2TT 307.2
God intends that, even in this life, truth shall be ever unfolding to His people. There is only one way in which this knowledge can be obtained. We can attain to an understanding of God's word only through the illumination of that Spirit by which the word was given. “The things of God knoweth no man, but the Spirit of God;” “for the Spirit searcheth all things, yea, the deep things of God.” 1 Corinthians 2:11, 10. And the Saviour's promise to His followers was: “When He, the Spirit of truth, is come, He will guide you into all truth. ... For He shall receive of Mine, and shall show it unto you.” John 16:13, 14. 2TT 308.1
God desires man to exercise his reasoning powers; and the study of the Bible will strengthen and elevate the mind as no other study can do. It is the best mental as well as spiritual exercise for the human mind. Yet we are to beware of deifying reason, which is subject to the weakness and infirmity of humanity. If we would not have the Scriptures clouded to our understanding, so that the plainest truths shall not be comprehended, we must have the simplicity and faith of a little child, ready to learn, and beseeching the aid of the Holy Spirit. A sense of the power and wisdom of God, and of our inability to comprehend His greatness, should inspire us with humility, and we should open His word, as we would enter His presence, with holy awe. When we come to the Bible, reason must acknowledge an authority superior to itself, and heart and intellect must bow to the great I AM. 2TT 308.2
