“Now Moses was eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh” (Exod 7:7).
Both Moses and Aaron had had crossed the age of retirement when God entrusted them to speaking truth to the powers of this world.

Moses brings to the job only forty years of experience shepherding his father-in-law’s sheep in Sinai desert. We do not know what Aaron was doing with his life. Nothing significant to mention. Five long chapters of the Book of Exodus (chapters 7 to 11) narrates their confrontation of Pharaoh who was the ruler of the mighty Egyptian empire in Late Bronze age.
They told Pharaoh that the king of the universe Yahweh has ordered that he should release the people of Israel from slavery. Since the Pharaoh was unrelenting a display of power ensued. Yahweh ordered Moses and Aaron to do miracles to prove that the creation is under his control, and he can use it to inflict Pharaoh’s kingdom. So, the ten plagues followed, until with the last plague Pharaoh had to let the people god.
Every Christian is called to speak God’s truth to the powers that govern this world. Silence is a horrible sin. A Christ follower should not keep quiet when the world runs contrary to its creator’s will. It could be a traffic jam created by processions or unruly drivers that hold up the ambulances carrying critical patients. Or it could be a civil servant who demands bribe. Make God’s truth heard by dialing the traffic police to remove the snarl or report the corrupt officer to the vigilance department.
Christ followers should do their part in cleansing their society from sloth, corruption, and evil. God says, “God and tell Pharaoh” Or “speak the truth to powers.”
Prayer: God help me to feel a divine restlessness so that when things go contrary to your ways, I may have the grace and courage to call a spade a spade.
