The Holy Spirit is the third person of the Holy Trinity – Father, Son, and Holy Spirit, and is Almighty God. As such, he is personal and fully God, co-equal and co-eternal with God the Father and God the Son. In every aspect of a Christian's life, the Holy Spirit is active. For example, one of the Holy Spirit's task is to give Believers a right and accurate comprehension of the Scriptures. 

The Advocate, Comforter, and Helper are terms we use to refer to the Holy Spirit. The Christian needs the assistance of the Holy Spirit in every aspect of life, for He comforts us, helps us, guides us, reminds us, teaches us, comes alongside us, counsels us, and intercedes and advocates for us.
