Free will seems to be quite the topic today. I must say it is a rather interesting talking point. For instance when we say that a person has a will is to say that a person experiences purpose, intends things, and makes decisions. Machines do not do that sort of thing, regardless how sophisticated they are. Artificial intelligence has come a long way but they're not there yet.
Discussion on free will is geared toward our ability as sinful human beings to accept Jesus as Lord and Savior. With that in mind to describe the human will as free is to say something about the way it functions. So to speak of the will as free when it comes to salvation we are using our free will in a proper manner. Be careful how you deny free will: you may very well deny the will itself.
When we use the term free will we are sayin that choices are involved. Certainly none of us believe that God would be pleased with having robots to serve him. I believe he wants people that love him and choose to serve him.
“If it is disagreeable in your sight to serve the LORD, choose for yourselves today whom you will serve: whether the gods which your fathers served which were beyond the River, or the gods of the Amorites in whose land you are living; but as for me and my house, we will serve the LORD.”
Joshua 24:15
