It is definitely predestination. There are many reason as to why it should not be free will. If we are saying Free Will, we are looking down on God because we are saying that we are the one who worked for the Salvation and not God who works our salvation. We were born sinners, our nature is to sin. By ourselves, we cannot see God. If God does not choose to appear to us and the holy spirit to convict us then how can we believe??? Believing in God is not just opening your mouth and say I believe. It is not just doing God's work. When you believe, you believe because you can see all of his works in your life. You believe because you can see clearly his power manifested in the world. If you say that just because you follow God blindly, you are believing in God then I will say that you must not have known who is Judas in the bible. Did Judas follow God? Yes he did. Is he going to heaven? I will say a definite NO. He followed God, but unfortunately, he did not believe in him. How can a belief be a matter of free will??? It is like saying that you can choose to believe that the sky is red when it is actually blue. It is like saying that you believe that you are an alien from another planet when you are not. Our believe in him is like a natural process, the more our eyes are opened, the more we believe. Our believe is definately not free will. Therefore we are not saved through free will
