What's God got to do with it?

To all my sincere Christian Arminian friends out there, who believe that man freely chooses to be saved, here are 2 serious question for you:

1. If man chooses to be saved, freely and of his own will without the help of outside influence from God the Holy Spirit moving on him, then why do you pray to God for someone's salvation? 

Let me put it another way. You believe God does not/won't violate man's will in the process of salvation, right? Then on what basis do you pray to God for someone to be saved? Borrowing from Tina Turner, "What's God got to do with it?", then? Isn't your position just wishful thinking?

2. Where is it written that man's free will is inviolable by God? Can you show me even 1 verse, or give me 1 example from scripture, that demonstrates that our wills/natures are taboo to God? Isn't your theological view actually putting man's will above God's in this one instance, thus making an idol out of our free choice/will? Doesn't this view point then make God subject to our wills?
