I would say that the will of man is not free in the sense of being able to choose his/her own decisions that are righteous, or unrighteous. Things that are good, or bad. In other words, there is something in the nature of humanity that naturally draws us to make decisions that are selfish, and what the Bible would declare is wrong (or, sin). It is like feeding a bail of straw to a lion in a cage. That lion would sit in the cage, and starve to death. It would not come across it's mind to eat the straw. It is not in it's nature. Likewise, humans, left on their own, will naturally make decisions that revolve around the self, and their own well-being, and are contrary to Scripture. I believe that it takes a drawing from the Spirit of God, and a change of the heart, for us to make decisions that are righteous and Godly. When becoming a Christian, the Bible teaches that the Holy Spirit dwells inside of you, and gives you the sense and ability to understand and make righteous decisions. The Apostle Paul describes our will before becoming Christians as being slaves to sin. Once a Christian, the Holy Spirit frees you from that slavery, and makes us a new creation. Although still influenced to revert back to our old ways, we have the ability, through the Holy Spirit, to make right decisions. To put it this way, before being a Christian we have an old pair of shoes on (representing the will that is not free, but naturally sinful). When the Holy Spirit changes us, we put on a new pair of shoes (we become new creations). We still may sometimes be tempted to put back on our old pair of shoes. Some may disagree with details of what I've said. But that is my view.
