Okay, so you are a universalist. Everyone saved in the end, not dependent on receiving the Holy Spirit in this life. All it takes (which I'm sure has already happened) is for one man or woman at some time in history to pray that no one be lost.
I'm not mad at you for being a universalist, by the way. Not going to scream at you or start a nasty.
What I desire and what actually happens can be two different things altogether. I would not tell anyone to go on sinning because I have prayed for their salvation as that would be a foolish thing to say and would harm the one that I would say that to.
It is clear in the bible that you must be born again to receive salvation. By that, my understanding is that you must confess you sins to God and repent, or in other words, change completely in your thoughts and actions in no longer preferring to live in sin. God is a God of justice and there must be a price paid for the sins committed. The price of this is God's son Jesus dying on the cross for these sins by His shed blood, and that by taking on the sins of the world he would experience the pain and suffering of having His father, whom He has always known, to turn his back on him. Jesus was dead for 3 days and nights, each day is as a thousand years in His eyes and a thousand years a day. That must have seemed like an eternity for Him as he suffered from the separation of the love of His heavenly father.
Is it wrong to pray for those that you love? Does not God love everybody and tells us as well that we are to love our enemies? If God were to answer only one prayer of mine I would chose that He answer the one that all be saved.
It is clear in the bible that all will not be saved. It is also clear that no one comes to the Father except through Jesus. This is a statement of biblical truth and will not be changed regardless of who or what one prays for including myself.
As I have said before, I believe that the entire Word of God will be fulfilled exactly as stated. In interesting thing though is perhaps the bible does not contain as of yet the complete Word of God because in the book of Revelation John was told not to write down what the Seven Thunders said, but yet all will be revealed at the proper time. Another interesting thing is what exactly did Jesus write on the ground with his finger while the crowd was ready to stone the woman caught in adultery? It is possible that what the Seven Thunders uttered and what Jesus wrote was pertaining to salvation and that may change the dynamic of what we currently believe regarding this matter and possibly many other matters as well.
Even so, whatever is revealed will not change a single iota of the Word of God for His word will stand. What may change however is our understanding of the Word of God. Rest assured though that the God that we know and love is a God of love. This will never change because God changes not.
