* Pharaoh’s magicians can imitate some of Moses’ early miracles, but they can’t stop the judgments. They can only make the problem worse!
* Persistent unbelief will lead to hardened hearts and eventually reprobation.
* If we fail to move/repent when the Holy Spirit is moving, we will harden our own hearts.
* When God speaks/moves… we had better listen and react.

Exodus 7:1   And the LORD said unto Moses, See, I have made thee a god to Pharaoh: and Aaron thy brother shall be thy prophet. 2 Thou shalt speak all that I command thee: and Aaron thy brother shall speak unto Pharaoh, that he send the children of Israel out of his land. 3 And I will harden Pharaoh’s heart, and multiply my signs and my wonders in the land of Egypt. 4 But Pharaoh shall not hearken unto you, that I may lay my hand upon Egypt, and bring forth mine armies, and my people the children of Israel, out of the land of Egypt by great judgments. 5 And the Egyptians shall know that I am the LORD, when I stretch forth mine hand upon Egypt, and bring out the children of Israel from among them. 6 And Moses and Aaron did as the LORD commanded them, so did they. 7 And Moses was fourscore years old, and Aaron fourscore and three years old, when they spake unto Pharaoh.

Exodus 7:8   And the LORD spake unto Moses and unto Aaron, saying, 9 When Pharaoh shall speak unto you, saying, Shew a miracle for you: then thou shalt say unto Aaron, Take thy rod, and cast it before Pharaoh, and it shall become a serpent. 10 And Moses and Aaron went in unto Pharaoh, and they did so as the LORD had commanded: and Aaron cast down his rod before Pharaoh, and before his servants, and it became a serpent. 11 Then Pharaoh also called the wise men and the sorcerers: now the magicians of Egypt, they also did in like manner with their enchantments. 12 For they cast down every man his rod, and they became serpents: but Aaron’s rod swallowed up their rods. 13 And he hardened Pharaoh’s heart, that he hearkened not unto them; as the LORD had said.

Exodus 7:14   And the LORD said unto Moses, Pharaoh’s heart is hardened, he refuseth to let the people go.

Hebrews 3:12 Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God. 13 But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin. 14 For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end; 15 While it is said, To day if ye will hear his voice, harden not your hearts, as in the provocation. 16 For some, when they had heard, did provoke: howbeit not all that came out of Egypt by Moses. 17 But with whom was he grieved forty years? was it not with them that had sinned, whose carcases fell in the wilderness? 18 And to whom sware he that they should not enter into his rest, but to them that believed not? 19 So we see that they could not enter in because of unbelief.
