Have you ever had someone die and you wish you could have another conversation with them?  I’m not talking about something demonic here like going to a medium.  But God had a plan for His people to carry on the mission of Jesus.  The disciples were going through a situation where Jesus was leaving, and they had to keep going.   Jesus had a way of still being with them.  He would send the Holy Spirit to take His place.  The Holy Spirt would be with them forever.
