God’s mind, being infinite, is impenetrable by finite beings. His thoughts are as much higher than our thoughts as the heavens are higher than the earth (Is. 55:9). How then can we know them? By ourselves we cannot. They are beyond us. There is no ladder by which we may climb to the heights of heaven, no way by which we may delve into the mind of God. But God has disclosed his thoughts to us by speaking. The Isaiah 55 passage continues: ‘As the rain and the snow come down from heaven, … so is my word that goes out from my mouth’ (verses 10-11). God has clothed his thoughts in words. His mouth has declared what is in his mind. Theologically we may say that revelation has come to us through the means of inspiration.
