Why does Moses' face shine?
INTERPRETATION 1: Moses has been in God’s presence for forty days.
According to Exodus 34:29, Moses’ face was shining “because of his speaking with Him.” Moses is taking on the characteristics of God. See Exodus 24:18.
INTERPRETATION 2: Moses has fully repented and is now 100% living by faith.
INTERPRETATION 3: Moses experienced a supernatural fast (e.g., no food and water for forty days). This changed the constitution of his heart and he was now fully receptive to God.
INTERPRETATION 4: Moses has been writing out God’s Words for forty days.
INTERPRETATION 5: Humans have a genetic property that allows the diffuse reflecting of light on their skin. See Genesis 3:1-7.
