No finite mind can fully comprehend the character or the works of the Infinite One. We cannot by searching find out God. To the strongest and most highly cultured minds, as well as to the weakest and most ignorant, that holy Being must remain clothed in mystery. “Clouds and darkness surround Him; righteousness and justice are the foundation of His throne.” Psalm 97:2. We can understand as much of His purposes as we are capable of comprehending; beyond this we may still trust the hand that is omnipotent, the heart that is full of love. TEd 101.1
The Word of God, like the character of its Author, presents mysteries that can never be fully comprehended by finite beings. But God has given in the Scriptures sufficient evidence of their divine authority. His own existence, His character, the truthfulness of His word, are established by testimony that appeals to our reason—and this testimony is abundant. True, He has not removed the possibility of doubt; faith must rest upon evidence, not demonstration. Those who wish to doubt have opportunity, but those who desire to know the truth find ample ground for faith. TEd 101.2
We have no reason to doubt God’s Word because we cannot understand the mysteries of His providence. In the natural world we are constantly surrounded with wonders beyond our grasp. Should we then be surprised to find in the spiritual world mysteries that we cannot fathom? The difficulty lies solely in the weakness and narrowness of the human mind. TEd 101.3
