Of course. We retain our free will. So what? I already dealt with this in my previous post.
Who said anything about coercion?
This seems to be your only focus, your only argument, which does NOT deal with salvation. You have target fixation, unable to see other scriptures that bear on the subject. This is why you say, "we are his workmanship BUT . . ." Either we are his workmanship or not. Paul said we are a creation in Christ Jesus. We are a creation. Let that sink in. The choices of those whom God is saving are definitely a reflection of the inwardness he is creating inside them. Thus, the sum and substance of salvation is a supernatural transformation of a person at the core of his or her being. Thus, Biblical warnings become the venue in which the saints demonstrate and practice the sanctification of the Holy Spirit.
You want to argue that the Bible contains warnings; and the presence of warnings logically implies both danger and failure. Given that mankind has free will, and given that mankind is weak and morally inept, then a falling away from the faith remains a logical possibility. Therefore one can lose his salvation.
But your argument side-steps the essential nature of salvation itself, which involves a divine commission, whereby God himself has decided to save someone. He is saving us, we are not saving ourselves. And don't let this view escape your notice. The Bible teaches us that God is an active agent, working constantly on our behalf, giving us enlightenment, moral training, and fruits of the Spirit. Your claim that such a person can fall away is patently absurd.
Your view totally ignores both the power and the work of the Holy Spirit in the life of those whom God is saving.
