Is it possible to be a True Worshipper of God if the Holy Spirit doesn't indwell you, if you're not born again?

That's a tough question. I received the Spirit when I met Jesus, without asking for it, so I only know that I am truly born again and spirit-filled. I believe all those who are true christians have the spirit, but I am not qualified to say who is or is not a true Christian. I don't believe that JW's are Christians because they deny the holy spirit.
