Exodus 19:18 Now Mount Sinai was completely in smoke, because the Lord descended upon it in fire. Its smoke ascended like the smoke of a furnace, and the whole mountain quaked greatly.
When God descended on Mount Sinai, He did so in a manner which not only shook the people but shook the mountain as well. God wanted their attention!
When God wants your attention, He will start by trying to get it gently but may well move on from that when you do not listen!
Are you still waiting with the crowd for God to shake your tree or shake your world?
Be careful you are not shaken out of your tree!
