Exodus 7:21 And the fish that was in the river died; and the river stank, and the Egyptians could not drink of the water of the river; and there was blood throughout all the land of Egypt. 22 And the magicians of Egypt did so with their enchantments: and Pharaoh's heart was hardened, neither did he hearken unto them; as the Lord had said.
Satan cannot impart life to either man or beast, but he certainly has the ability to make it seem so, for the sole reason that human beings are not able to discern the difference, without the power of God. In other words, he did not create any real fish, frogs or serpents, but, for all intents and purposes they did appear to be real, and genuine to the human eye.
In addition to this, very many of the capabilities that holy angels have, devils also have. This may be quite disconcerting to hear but it’s the truth. For instance, holy angels could specifically single out one or more persons in a congregation, and could visibly appear to them while persons around do not see, nor hear anything.
Daniel 10: 4 And in the four and twentieth day of the first month, as I was by the side of the great river, which is Hiddekel; 5 Then I lifted up mine eyes, and looked, and behold a certain man clothed in linen, whose loins were girded with fine gold of Uphaz. 6 His body also was like the beryl, and his face as the appearance of lightning, and his eyes as lamps of fire, and his arms and his feet like in color to polished brass, and the voice of his words like the voice of a multitude.
Daniel 10:7 And I Daniel alone saw the vision: for the men that were with me saw not the vision; but a great quaking fell upon them, so that they fled to hide themselves.
May God add His blessing to the study of His word. “Good night” and God bless!
