Strike one! He desires those he set out to save to be saved, and none other. So, that's not speaking of all people at all times. Your tradition has caused your bias, misinterpretation and error.
Strike two! Look at the context. Who came to see Jesus? His word is to them and those of every other tribe and nation he would draw, not each and every person who has ever lived.
So now you're a Universalist. Here's what you're saying, and it's a huge mistake, and this is going off the gist and context of each above: you're stating that every single person will call upon the LORD and be saved, this is conveyed by your saying "that's everyone." Well, guess what, it's not everyone.
"And you're out!"
You really, really need to leave your rudimentary verse-ology pretext understanding and graduate to context and a clear understanding of what is really being said. If that offends you then you're just too prideful and are unwilling to employ proper context. You may lose a few fans if you do so.
What is the context of the "us/you" here; 2 Peter 3:9? Are you ready to humble yourself and use it, or not?
Hint: look at the audience that Peter refers to from chapter 1 and throughout this epistle. There is no way around it, he is always referencing the elect in this, and none other and he is still addressing them in 3:9. You really need to start employing proper context. 2 Timothy 2:15. Please.
That, and you're conflating a couple of texts together.
