Exodus 6-10 tells us about the plagues in Egypt. Exodus 6:7 God tells us why He worked through plagues, “Then you will know that I am the Lord your God”. We see in the previous chapter that the Israelites had lost trust in God and confidence that He was going to do anything to help them….because things were getting worse. They had been in Egypt for 400 years and forgotten their God and His ways.
Exodus 7:5, “the Egyptians will know that I AM the Lord.”
Exodus 8:10…Moses speaking to Pharaoh…”so that you may know without any doubt and acknowledge that there is no one like the Lord our God.” Pharaoh worshipped many gods and also thought himself a god.
Exodus 9:15-17, “for by now I could have put out My hand and struck you and your people with a pestilence, and you would have been cut off/obliterated from the earth. But, indeed for this very reason I have allowed you to live, in order to show you My power and in order that My name be proclaimed throughout all the earth. Since you, Pharaoh are still so arrogantly exalting yourself in defiance against My people by not letting them go hear this….”
Exodus 10:1-2, God speaking to His people…”so that I might exhibit My signs of Divine power among them, and so that you may recount and explain in the hearing of your son, and to your grandson, what I have done repeatedly to make a mockery of the Egyptians – My sings of Divine power which I have done among them – so that you may know without a doubt and recognize clearly that I AM the Lord.”
This also gives us insight into why God uses plagues in the future as described in the book of Revelation. He is demonstrating His absolute power and authority, as well as His ability to separate His people from those who are not with Him. For His people, God is giving evidence of His Lordship so that doubts are removed…and also an eternal testimony and reminder that He is a powerful Redeemer!
For those in the world (Egypt), He is giving evidence that He exists and is above any other god or idol, plus He is giving opportunity to repent, change hearts and minds to join Him and the redeemed! For Satan (Pharaoh), whose mind and heart is already so hardened and for those who side with evil, God is demonstrating His supremity with His Word of grace (opportunity to change sides) prior to justice and judgement. There will be no more deception, doubt, or confusion….all will be made clear. Everyone will see and know….He is Lord!
