The lesson takes up the problem of defining God. To define something is to limit and comprehend it, but God is infinite and incomprehensible, so a God who could be defined would be no God at all. When Moses asked what name he should give the people, God answered, “I AM WHO I AM,” and called Himself the LORD, the God of Abraham, Isaac and Jacob.
The study explains that God’s name is not a label or description but a statement of His incomprehensibility. He is the source and definer of all things, who governs and is not governed by man. Yet He is not silent. God reveals His being and nature in history, in creation, in His written Word and supremely in His incarnate Word. His revealed name is the only name man can know, and it is His memorial to all generations.
