Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
No matter what the disciples of Christ would face, they would not be left without help and comfort. Christ would send the Holy Spirit to be their Helper. It was to the advantage of the disciples that the Helper should come. He would empower them, give them courage, teach them, and make Christ more real to them than He had ever been before. The Helper would not come until Jesus went back to Heaven and was glorified. Once the Holy Spirit came, He would be with them as long as they were on the earth.
