What the Bible says, God, says. The foundation of what we know to be true about the Bible is the inspiration or expiration of Scripture. It comes to us from God.
If we want to know God and see His glory His character, His person must be revealed to us. Moses asked God to see His glory but Moses heard more than He saw. He saw the back of God but He heard a beautiful, glorious declaration of God’s character. This is our God.
