Some Tulip calvinists such as John Piper interpret the I Timothy 2:3-4 passage as meaning every individual in the world- past, present, and future. Others see this passage meaning all classes of men just as they interpret John 3:16 'world' meaning. Piper wrote an article: Does God have two wills? He basically is saying the Arminians are right about the Timothy verse - God does desire ALL men (that is every solitary individual -past, present, and future) to be saved and come to the knowledge of truth. That is why the Gospel is offered to all people.
