Many Christians will read Job Chapter 41 and come to the conclusion that Leviathan is a dinosaur or an alligator based on the description of Leviathan. However, further study into Leviathan would conclude without a doubt that Leviathan is just another form of Satan. Just as Satan is also known as a Serpent or a Dragon..etc. Martin Luther, Peter Ruckman and anyone that believes what their Bible says also hold to this belief. We will study the Bible and show how it cannot possibly be an animal.
Now let's study what the Bible says about Leviathan.
33 Upon earth there is not his like, who is made without fear.
34 He beholdeth all high things: he is a king over all the children of pride.
This description clearly and accurately fits Satan. "A king over all the children of pride"? Only Satan would fit that description.
19 Out of his mouth go burning lamps, and sparks of fire leap out.
20 Out of his nostrils goeth smoke, as out of a seething pot or caldron.
21 His breath kindleth coals, and a flame goeth out of his mouth.
This is clearly a description of a Dragon. And Satan is called a Dragon in Revelation 12:3,4,7,9,13,16,17 and 13:2
Revelation 12:3 says that Satan (dragon) has many heads
And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.
Now let's take a look at what Psalms 74:14 says about Leviathan
Thou brakest the heads of leviathan in pieces, and gavest him to be meat to the people inhabiting the wilderness.
There is not a single animal on earth which has more than one head. An alligator does not have multiple heads and neither does a dinosaur. This can only be Satan as it matches Rev. 12:3 and also matches when Jesus will crush Satan's head at the 2nd Advent (Contrary to popular belief this did not happen at the first advent)
And the God of peace shall bruise Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen.
Notice Paul says God will bruise Satan in the future tense. The book of Romans was written long after Calvary so this proves the point (however, discussing this deserves a post in itself)
And now let's compare Romans 16:20 with Genesis 3:15
And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
So Psalms 74:14 which I quoted above is clearly speaking of Satan when you compare scripture with scripture.
And now we will look at what Isaiah 27:1 has to say about Leviathan.
In that day the LORD with his sore and great and strong sword shall punish leviathan the piercing serpent, even leviathan that crooked serpent; and he shall slay the dragon that is in the sea. (Read the whole context of Isaiah 27 and you will see it is speaking of the 2nd Advent)
This verse is a prophecy about when Jesus destroys Satan and bounds him for 1,000 years prior to the Millennium. Even babes in Christ know that the serpent is Satan and this verse clearly establishes that Leviathan is not only a serpent. But, he is also a dragon, which is exactly what Satan is!
