Chapters 12 & 13 deal with the anointing at Bethany, the triumphal entry and the Last Supper. In Chapters 14-16, we have the teachings of Jesus about the Holy Spirit as the helper, comforter and advocate. The Holy Spirit is a person of God, just like the Father and the Son. We see that the Father, the Son and the Holy Spirit were all present at Creation, as well as at the baptism of Jesus. The Holy Spirit has a mind, a will, and emotions. He dwells in us when we get saved. He teaches, convicts and guides us, as well as testifies through us.
