The big question in this whole debate is how does God choose?
Calvinism falsely claim that it is before the foundation of the world. No Scripture to support that except a twisting of Eph 1: 4.
What does the Bible really say about how God chooses?
Acts 10: 34-35, "Then Peter opened his mouth and said: “In truth I perceive that God shows no partiality. But in every nation whoever fears Him and works righteousness is accepted by Him.
That word "accepted"; that's being chosen. Was that done before the foundation of the world? Not according to Peter's statement.
So we see, from Scripture itself, that God chooses a person based on that persons heart response towards Him.
Acts 13: 22, "And when He had removed him, He raised up for them David as king, to whom also He gave testimony and said, ‘I have found David the son of Jesse, a man after My own heart, who will do all My will.’
Men choose, of their own free will, to either respond to or resist the Holy Spirit.
That's how God can be just in judging them. Calvinism is detestable.
