We always want to be at the right place at the right time

On the day of Pentecost there were 120 people in the upper room waiting on the promise that Jesus had given them.  I thought Jesus served thousands upon thousands of people.  Didn't the Lord Jesus hold a sermon on the mount to a multitude.  Where were all of these people at on the day of Pentecost?  We don't know where they were at.  I am sure that some of these people were very much affected by the sermons of the Lord Jesus and that these words of our saviour impacted their life.  However, on the day of Pentecost we know that those people who were not in the upper room were at the wrong meeting.  As God's children we want to make sure that we let God direct the sheepfold that we are to be apart of and that He directs our steps so that we are at the right place at the right time.  (Acts 1:15)
