Without faith, it is impossible, to please our Lord.. When the Word declares in Is.24:13 the "shaking as of an Olive Tree" this a symbol for one group. Hebrews 11 covers faith very well. People that claim to be Followers are not listening or Believing.
Our Lord promised to scatter the Descendants of Sarah throughout the earth-done. Because of a loss of identity, this group doesn't have a clue of their heritage: and have become quite comfy in their lives. But God!
What does a Shaking look like? Look around. 1Kings 14:15 - a "Shaken" and "Scattering". Do not over-look the word grove in this verse. Shaken = a motion produced by the winds, storms, waves etc. To agitate. To move. Agitate the mind, to disturb one.
Groves was a special place of Idol worship of Ashe-rah goddess: Easter came out of this. Sluggards enjoy entertainment at the expense of others - sports has become the religion of choice. It is not personal, or chance that sports is being Shaken.
Matt.11:7 shows that their are plenty of shaking, shaky, shaken people on the earth: They thought John was another one of them. A reed shaking in the wind; whichever way the wind blows... The Truth grounds us. Too many waver, or aimlessly wander; moving to and fro, fluttering.
