I tend to agree. I don't see how freely choosing to believe the Gospel and Jesus as Son of God is or can be seen as any kind of work, anyway. What's there to brag about? What's there to say that you worked for your salvation in simply responding positively to the Holy Spirit's calling?
I just don't get this Calvinistic thinking that the OP seems to suggest, that people who choose to believe when prompted have suddenly made the Gospel about themselves and not God or something, or that God's sovereignty is threatened or undermined in any way. Again, what is the work or thing to be proud of in any way in simply saying "Yes, Jesus! I would love to have this gift that You freely offer! Thank you!" Well, whoop-tee-do, what a great work we mortal shave done in this (note my sarcasm). How does that mean we will suddenly think we have saved ourselves and end up taking Jesus or God the Father out of the equation? Or turned salvation into something we earned through the mere obedience of believing? We don't earn it; eternal life and forgiveness of sins is something freely offered, and we accept or reject it, more or less. And regardless of the choice we make, God is still God and in control.
