Most people believe that Satan appeared in the Garden of Eden as a serpent and tempted Eve to commit sin. Some point out, however, that the Genesis account does not directly identify the serpent as Satan, and others will actually argue against the serpent being Satan. So am I knowing and willfully opening this potential Pandora’s box? Oh yeah.
I suggest beginning with a read of Genesis 3. In verse 15, God speaks of enmity between the seed of the serpent and the seed of the woman. This makes little sense if God is speaking to a mere serpent. But if the seed of woman is a veiled reference to the Son of Man, i.e. Jesus who is the Christ, then this is the first prophesy of the Messiah. My readers already know I believe this to be true. If Genesis 3 is the first mention of a future salvation, then the serpent must be Satan, the Devil, whom Jesus will ultimately defeat and cast into the lake of fire.
The next thing I wish to do is acknowledge Troy Lacey and the website AnswersinGenesis.org. This article is the most concise listing of the scriptures making this case that I’m aware of. Lacey begins with Genesis 3 as I have above. He then goes to Ezekiel 28, and includes linkage to some back story on how this passage may be interpreted. If you conclude that Ezekiel 28 address the fall of Satan from glory and his future demise, then notice verse 13 that says “you were in Eden.” No kings alive during Ezekiel’s time (nor any human being besides Adam and Eve) could have been in the Garden of Eden. Like many Bible prophesies, Ez. 28 refers to events that are both near and far in fulfillment. The prophesies listed are only somewhat fulfilled in the destruction of the actual prince and king but describe the already and future demise of Satan. Similarly with Isaiah 14.
Finally, the Revelation refers to Satan three times as a serpent. (Lacey links each occurrence, be sure to read his article.) Rev. 12:9 offers the best support that Satan and the Garden serpent are one in the same:
And the great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world—he was thrown down to the earth, and his angels were thrown down with him.
The Bible never says the devil was the Genesis 3 serpent; but Satan is called the ancient serpent in Revelation. Notice the ancient serpent/devil/Satan, whatever name he is known by, is the deceiver of the whole world. At the time of outcast from Eden, Adam and Eve were the whole world. And after being cast from Heaven the earth, this plane of existence, has been home to Satan. When God placed Adam and Eve in the Garden he knew that it was already the dwelling place of Satan and his angels.
Was the serpent in the Garden of Eden Satan? I believe it was. Does the Bible say so? I believe it does; what do you think?
