"But this man, after He had offered one sacrifice for sins forever, sat down..."
Jesus; after doing all that He did, sat down. Don't you love it?! This man lived in peace. He was not driven out of a compulsion to 'do something', but simply did what His Father asked Him to... and then sat down. What relief, to me anyway as I have not always been too good with the 'sitting' part of life.
The key is in listening to God's voice and knowing that His purposes are to be mine. There is no room for striving in this equation.
