A false dilemma would'nt allow and even ask you to provide your own choice would it? I did, which I notice you conveniently didn't do. If not one of these options, which one? There has to be a cause for that choice to reject or accept Calvinism within a deterministic system, right? So, why? What causes it?
Its not a dilemma for us because we affirm free will (LFW). We believe in self-determiniation. I determine my choices. God created me with the ability of first cause choices...i.e. choices not caused by Him. I determined to be Arminian, not God. If I'm wrong its my responsibility because it was my choice. I could have done otherwise because nothing prevented me from seeing and understanding the truth and responding to it.
Since you deny the possibility of LFW you cannot say this. You must either say (1) we don't accept Calvinism because we aren't really saved or (2) we don't accept Calvinism because God didn't grant the grace to some of His children to accept it, while he did to others. There is really no other option unless you affirm LFW.
There you go again. You started this post off denying that you present false dilemma because you leave the door open for another option.
Then you present the EXACT same false dilemma in the exact same post and SLAM the door for that other option at the end of the post.
Your "first cause" argument is illogical and totally void of Scriptural support. Not only, though, is it lacking in biblical support but it also contradicts a host passages and a superabundance of Scriptural evidence that God alone is the ultimate cause of all things.
I have presented many of these passages in previous exchanges.
The problem with your position is that "ultimate cause" and "first cause" are the same thing.
Man CANNOT be the ultimate cause of ANYTHING. He CANNOT be the Prime Mover of ANYTHING. He cannot create anything or cause anything or author anything "ex nihilo".
Only God can do this.
