You don't cooperate with grace. It is given to you by doing nothing. Grace is believing that Jesus did it all by faith. If you don't believe that, then it's not grace. No one will be able to boast about one thing they did or didn't do for salvation.
This was already addressed...
Post 1365 addressed the subject of cooperating with God's grace.
You (faithplusnothing1) discounted that in your post 1375 through use of a defective definition of the word "grace" (I don't hold it to your fault...I'm aware that there are many sects that teach that)
I then provided you two sources (btw both of them Protestant) for an accurate definition of grace (Strong and Thayer) in post 1398.
You might want to review those definitions again. I note that you didn't bother to respond to post 1398 earlier, so I figured you must have agreed with me. I guess not.
So what do you do with the concept of free will?
