And God said to Moses, “I AM WHO I AM.” And He said, “Thus you shall say to the children of Israel, ‘I AM has sent me to you.’”
He Is There and He Is Not Silent (1972) is one of the many popular books of the late theologian Francis Schaeffer (d. 1984). In that book Schaeffer set forth biblical arguments for two truths: God exists and He has spoken with a clear voice to mankind.
When God called Moses to lead the Hebrew slaves out of Egypt, he raised both those important issues. Anticipating questions the Hebrews would ask him, Moses asked God who he should say was sending him and what name He is called by. The questions were understandable—the descendants of Jacob had been trapped in Egypt as slaves for 400 years. They could be forgiven for wondering if God would ever speak to them or help them again. But God was there and He was not silent. He told Moses to tell the people that His name is “I AM”—a statement of His sovereign existence. Fortunately, the Hebrew slaves believed Moses and listened to God’s voice.
Fifteen hundred years later, the writer to the Hebrews told his readers, “Do not refuse Him who speaks” (Hebrews 12:25). As you study God’s Word and the Spirit quickens it to your heart (Romans 10:17), do not refuse Him who speaks.
Listening to God’s voice is the secret of the assurance that He will listen to mine.
