The Cat Illustration: A Lordshipper's Attempt to Prove His False Belief

I recently heard Matt Mason of Lion of Fire Ministries illustrate why he believes that good works in a person's life are necessary to prove salvation. He said that the way he explains it is to tell people, "A cat meows. Meowing doesn't make it a cat. But because it's a cat, it will meow." Matt Mason says that if a cat is a real cat, it will meow. That's how he illustrates his view that if a person is a real Christian, he or she will do good works. Matt says that it's not how many good works a person does (or doesn't do) but rather that they will do some. 

Well, that is at least a nice attempt to illustrate his belief. But there's a glaring problem with Matt Mason's cat illustration. And it's simply this: A cat is still a cat even if it never meows! This is plainly obvious. If a cat never meows, are you going to say it's not a cat?! That's ridiculous. No sane person would ever say that. Rather, they would either say: "I wonder what's wrong with this CAT that it never meows?" Or they would say, "Why isn't this cat meowing?" Only an idiot would take their cat to the vet and say, "I thought this animal was a cat, but it's not meowing. Since it's never meowed a day in it's life, I'm now convinced it's not really a cat!" Get ready to call an ambulance because the vet just might die laughing!
