Who is the Holy Spirit and what does He do? There’s a lot of misunderstanding about Him and His role. At the end of Jesus’ life, He taught about this. The Holy Spirit is key to the abundant life that Jesus promised.
“And I will pray the Father, and He will give you another Helper, that He may abide with you forever— the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you. I will not leave you orphans; I will come to you.” – John 14:16-18
