In John 15:26 to 27 It says
"But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me:
27 And ye also shall bear witness, because ye have been with me from the beginning."
In these scriptures Christ is speaking to his apostles and promising them the guidance of the Holy Ghost. It is unknown whether his apostles actually understood what Christ was saying. (I personally believe they had no clue.) They were so accustomed to being around Jesus and having the ability to ask him about their concerns that the idea of some unseen being might have seemed unreal. Yet, just like his prophesy’s of His death and betrayal came to pass, this also came to pass.
What, or shall we say who is the Comforter? The Comforter is the Holy Spirit. He is not Christ. While Christ and the Spirit have the same purpose and goal, their bodies are separate. Since the Spirit has no body his mission is special. He can touch spirits. Through this ability he is able to comfort us when we are sad, guide us when we feel lost, and tell us what we ought to do.
What an amazing reality. While Christ had to leave this earth, he sent the other part of the God- head to stay with us. The spirit can be felt by everyone as they do good things. It is the good feeling that one gets when one serves another, prays, or sacrifices. Yet, if we want to have the spirit guide us every day there is a requirement. We must accept baptism and live according to the laws of God.
I am grateful for the spirit. I have called upon its comfort daily and have become stronger through its promptings.
