I'll try give you the short version but its a an indepth subject
Total Depravity this is the belief by those who embrace Calvinism, one thing: God has always been a God who provides choices. For example,
Deuteronomy 30:19 says, "...I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live."
After reading this verse, it becomes apparent that mankind has the ability to make the proper choice with respect to salvation.
Even after Adam and Eve ate the forbidden fruit, Genesis 3:22 described them as follows:
"And the LORD God said, Behold, the man is become as one of us, to know good and evil, etc."
Genesis 3:22 reveals that, after Adam and Eve sinned, they knew both good and evil. And Deuteronomy 30:19 indicates that mankind still had the ability to choose either life or death.
This proves one thing: even though mankind is considered spiritually depraved, this doesn't necessarily mean that we are totally incapable of making the correct choice with respect to our own personal salvation.
Keeping this in your mind, look at Calvinism's misconception of mankind's total depravity:
According to them, mankind's spiritual downfall prevents everyone and anyone from making the proper choice regarding salvation. They believe that it is impossible for us to come to God on our own. However, this position seems to be in clear contradiction to the Scriptures.
Once again, Deuteronomy 30:19 provides the evidence because, if man was totally incapable of making the correct decision to choose life, why would God say to choose? It doesn't make any sense, does it? In fact without choice we are just puppets playing out some game for no reason at all..
It all begins with God. He has instilled a conscience in every single one of us. Based on our consciences, we make the choice. Since God has foreknowledge, He just happens to know the decisions we will make before we make them. It's that simple!
According to Calvinism, God has unconditionally or arbitrarily elected those to be saved before the foundation of the world solely on the basis of the counsel of His will, not taking anyone's accountability into consideration.
As a result, no matter what anyone does, if God didnt Elect them before hand all the rest are pre-destined to damnation.
This view is not only without merit, but also quite ludicrous. It takes away Grace and gives it a qualification not stated in scripture. According to Calvinism, as far as God is concerned, the rest can burn in hell...and God doesn't care!
This doctrinal positions insult God’s very nature and character to the highest possible degree, portraying Him as a sadistic monster.

P.S, do not get me wrong I do believe there is a number of pre destined Elect ..I just do not believe no matter how faithful a servant you try to be if your not predestined your of no use to God so your damned to hell anyway... If that were the case there would just simply be no reason to be here God would have chosen his favorites and ended it long ago. We would not need grace.
