And the LORD said unto Moses and unto Aaron, Take to you handfuls of ashes of the furnace, and let Moses sprinkle it toward the heaven in the sight of Pharaoh.And it shall become small dust in all the land of Egypt, and shall be a boil breaking forth with blains upon man, and upon beast, throughout all the land of Egypt Exodus 9:8-9

Now comes time for the 6th Plague, as were seeing each plague is a little different and they each are revealing to the Egyptians how their pagan gods are useless and their rejection of the true living God has serious consequences. 

Again we see a parallel of this plague in Egypt and in Revelation. Its very clear the God of the Old Testament is the same God of the New Testament, anyone who thinks otherwise should study the Plagues of Egypt and the Wrath of Revelation

Again were seeing a Plague that will torment people, and again we see God separate the Wrath from Egyptians and Israelites. Is this a foreshadow of the Rapture? Either way God is in complete control!

And they took ashes of the furnace, and stood before Pharaoh; and Moses sprinkled it up toward heaven; and it became a boil breaking forth with blains upon man, and upon beast. And the magicians could not stand before Moses because of the boils; for the boil was upon the magicians, and upon all the Egyptians. Exodus 9:10-11

This time the torment was so bad, the magicians of Egypt couldnt even try to reproduce the miracle God had performed. What will it take for  people to come to repentance? Why do we allow our pride to rule our hearts instead of Christ?

And the LORD hardened the heart of Pharaoh, and he hearkened not unto them; as the LORD had spoken unto Moses. Exodus 9:12

Even though the Egyptians see the true living God revealed, Pharaoh still refused to repent. We see this alot in people today, they want to enjoy all the attributes of God but they dont want to acknowledge God. Everybody wants love, peace, joy, everyone stands in awe of the universe, the ocean, DNA, however they still deny the Creator

And the first went, and poured out his vial upon the earth; and there fell a noisome and grievous sore upon the men which had the mark of the beast, and upon them which worshipped his image. Revelation 16:2

Again as you study the bowls of wrath of God in Revelation , you see how they parallel the plagues of Egypt. Here God gave the same judgement, but this time poured unto the entire Earth.  You would think that after all these judgments and revelation of Gods power, people would recieve God however as we see with the Egyptians and we see below, many people still wont repent

And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give him glory. Revelation 16:9

How does the wicked respond to Gods wrath? They blasphemy his name and refuse to give him any glory or credit. Is this an evidential issue with God? Absolutely not, this is a heart issue. People pride and love for sin, they harden their hearts and suffer the wrath of God!
