In a word: no. Snakes do NOT talk. Donkeys do not talk. There are no such such things as dragons or unicorns. The throat of a whale is not wide enough to accommodate a human being, who would be caught in the baleen which strains out tiny sea creatures from the water ingested.
Let me try this again. Satan wasn't a snake when he tempted Eve. He was made into a snake as punishment for what he did.
Gen 3:14
And the LORD God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:
He was called a serpent in Genesis and Revelation.
Gen 3:1-4,13
Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?
And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:
But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.
And the serpent said unto the woman, Ye shall not surely die:
And the LORD God said unto the woman, What is this that thou hast done? And the woman said, The serpent beguiled me, and I did eat.
Rev 12:9
And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
Rev 20:2
And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,
Do dogs have vocal cords, because I have a friend whose dog could talk real good. It doesn't really matter, because I believe that if God wants a serpent or a donkey to talk, then it will.
I also believe that if people want to try and use stuff like this to prove that conservative/fundamentalist/protestant are dumb, closed minded whatevers, then they will.
If they think that changes what is or isn't a sin, well it won't.
I also don't believe that those who are really seeking the truth, and may be reading these post and not posting, will all fall for this method of trying to discredit people.
We are just to plant the seeds of truth, and the Lord will take care of the rest.
So yes the Bible means what it says when taken as a whole and in context. Reading the Bible prayerfully, asking the Lord to give you wisdom and understanding will happen just like the Bible says it will.
We will be given eternal life with the Lord if we accept His gift of salvation and mercy, by faith. We will be forgiven of our sins if we repent and confess them, again just like the Bible says He will. We will one day go and live with Him in the mansion He has prepared for us, just like the Bible says.
I could go on, but I might accidently state one of the truths from the Bible that isn't accepted by all, and I may have already done that since the Bible is so questionable.
P.S. Oh by the way the Bible says a great fish, it doesn't say anything about a whale.
