Just as Jesus is called... Christ, Redeemer, Savior, Son Of God, Son of Man, Prince of Peace, Word of God, Bread Of Life, Bridegroom, King Of Kings, Lord of Lords, Apostle, Chief Shepherd, and our High Priest, and Lord!...All of which indicate various functions and capacity He possesses in His Relationships with us... so it is consistent and proper that various names would be given and used in connection with the Holy Spirit's ministry in our lives.
