Free will is never used in the context of Salvation.
It is God who decides. Three times in Scripture we read God saying “I will have mercy on who I will have mercy.” We see god picking individuals, groups and a country. We see God tell us He is the potter and we are clay. God chides us when we question his elective purpose. He brings us to life. he turns out stone hearts to flesh. He brings our dead bones to life. He gives us a new birth.
No my FRiend, God chooses us. We are at war with him until he brings us to life.
John 3:16 and Romans 10:9-10. God knows who will be saved, God chooses who will be saved, and we must choose Christ in order to be saved.
