By faith he forsook Egypt, not fearing the wrath of the king; for he endured as seeing Him who is invisible.
Moses forsook Egypt twice: the first time in fear for his life after killing the Egyptian taskmaster (Exodus 2:11-15), and the second time, fearlessly leading the Israelites out in the Exodus.
Throughout his many trials, Moses endured by doing the impossible—seeing the invisible! This is the spiritual insight that has strengthened God’s people through the ages when their faith was under attack (consider 2 Kings 6:14-18 for one amazing example).
Consider also Paul’s prayer to strengthen the Ephesians: “The eyes of your understanding being enlightened; that you may know what is the hope of His calling, what are the riches of the glory of His inheritance in the saints, and what is the exceeding greatness of His power toward us who believe, according to the working of His mighty power” (Ephesians 1:18-19).
