No. We must agree to making "the change". Now, whether God draws us to that change in a Calvinist way or not is another discussion, but regardless, I don't see repentance as a work.
Calvinist= He has not drawn them to Him.
Arminian = They have not made a "decision" for Christ.
Does that answer it? I'm not sure where you're headed.
I feel you avoided the direct question. Did the prodigal choose to repent? If so, how did he repent? And how is that repentance not a work?
