Many people misunderstand predestination. Each person has a free will to make a choice to either believe or reject Christ and the gospel. Then comes predestination, all those who accepted Christ are predestined to be conformed to His image to be like him - Rom 8:30, Those who reject Christ are predestined to eternal separation from Christ in the Lake of Fire. Paul's sermon in Acts 13:46 places responsibility on those who reject Christ, "Paul and Barnabas spoke out boldly and said, “It was necessary that the word of God be spoken to you first; since you repudiate it and judge yourselves unworthy of eternal life, behold, we are turning to the Gentiles. God is not willing that any should perish, but that all should come to repentance.
