"They ... sought him with their whole desire, and he was found of hem: and the Lord gave them rest round about" (2 Chronicles 15:15)
There is nothing eerie, nothing queer, nothing contrary to the normal operations of the human heart about the Holy Spirit. He is only the essence of Jesus imparted to believers. You read the four Gospels and see for yourself how wonderfully clam, pure, sane, simple, sweet, natural and lovable Jesus was. Even philosophers who don't believe in His deity have to admit the lovableness of His character.
You must be sure of all this to the point of conviction. That is, you must be convinced to a point where you won't try to persuade God.
You don't have to persuade God at all. There is no persuasion necessary. Dr. Simpson used to say, "Being filled with the Spirit is as easy as breathing; you can simply breathe out and breathe in."
Jesus, breathe Thy Spirit on me,
Teach me how to breathe Thee in,
Help me pour into Thy bosom
All my life of self and sin.
