Speaking of chairs, did you ever notice that the Tabernacle from the book of Exodus had no chairs? There were other pieces of 'furniture'. There was a table, and a lamp. No chairs. The priests worked and worked serving God.
Then the Bible talks about Jesus coming as the Great High Priest, offering himself as the Lamb, and sitting at His Father's right hand! Alleluia! The work it done. It is finished. Christ completed the work of salvation...and sat down. :)
