Now the LORD spoke to Moses and Aaron, saying, "When Pharaoh speaks to you, saying, `Work a miracle,' then you shall say to Aaron, `Take your staff and throw it down before Pharaoh, that it may become a serpent.' " (Exodus 7:8, 9)
Moses and Aaron had obeyed the command of the Lord and had spoken to Pharaoh to release the Israelites. But Pharaoh said, "Who is the LORD that I should obey His voice to let Israel go? I do not know the LORD, and besides, I will not let Israel go." (Exodus 5:2)
Moses and Aaron pleaded with Pharaoh, but instead of releasing the Israelites, he made them work more harder and stopped providing them with straw to make bricks. Their foremen were beaten. The foremen in turn poured out their anger on Moses and Aaron by blaming them for this sudden worsening of their working conditions.
Moses was discouraged and complained to the Lord,
"O Lord, why have You brought harm to this people? Why did You ever send me? "Ever since I came to Pharaoh to speak in Your name, he has done harm to this people, and You have not delivered Your people at all." (Exodus 5:22, 23)
God again commanded Moses and Aaron to go to Pharaoh. He promised to do a miracle. When Aaron threw his staff down in the presence of Pharaoh, it would become a serpent. And that is exactly what happened. But other things happened that God had not revealed to Moses and Aaron.
Then Pharaoh also called for the wise men and the sorcerers, and they also, the magicians of Egypt, did the same with their secret arts. (Exodus 7:11)
Each one threw down his staff and they turned into serpents. That really must have startled the brothers Moses and Aaron. Something that God did not reveal to them. For a moment they must have wondered what was happening, whether God Almighty was in control, but soon their doubts were cleared when they saw the power of God manifested in front of them. The Bible says,
Aaron's staff swallowed up their staffs. (Exodus 7:12)
Moses and Aaron must have immediately realized that the power that they had with them was greater than the power that the magicians and Pharaoh had.
The Bible says,
You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world. (1 John 4:4)
John the Apostle here is speaking of the spirit of the Antichrist that is in the world. No doubt like the magicians of Egypt, the satanic spirits have power but there is a far greater and higher power in you and me who have accepted Jesus and Christ.
Like Aaron's staff could swallow the staffs of the magicians, the power of the Holy Spirit in every believer overcomes the power of the the evil one who is in the world.
Always remember, the one who is in you is greater than the one who is in the world. So do not fear.
