If you want to have fellowship with the Holy Spirit, firstly, you must know that even a little sin in front of the Lord makes such a fellowship impossible. You might think, ‘How can a man have not even a bit of sin in front of the Lord?’ But if you truly wish for fellowship with the Lord then there should be no darkness in your heart. Therefore, in order to have fellowship with the Lord, you need to know that you must believe in the gospel of redemption and cleanse yourselves of all sins.
