"Are men free to choose this or that form of society for themselves? By no means. Assume a particular state of development in the productive forces of man and you will get a particular form of commerce and consumption. Assume a particular stage of development in production, commerce and consumption and you will have a corresponding social structure, a corresponding organization of the family, of orders or of classes, in a word, a corresponding civil society. Presuppose a particular civil society and you will get particular political conditions which are only the official expression of civil society."That is who is presuming that mankind has no free will.
Karl Marx
For those who think we do have free will even when God enables us to choose.
The only FREE moral agent in the universe is God. He's the only one who can act without any outside influence working on Him.
Sure we have will. It just isn't free.
We can't even begin to know God without Him quickening us, without His intervention.
We are spiritually dead so spiritual truths are non-existent to us. We cannot perceive them because we don't have the capability to. The spiritual part of us that was created to perceive spiritual reality died.
No one can perceive what they are unequipped to perceive. Blind can't see light, deaf can't hear sound, spiritually dead cannot perceive spiritual reality.
So we are not free to choose because without help we CAN'T. We are not FREE moral agents acting without outside influence.
You can quote Marx to support your position. I'll quote Scripture.
