This chapter is about Daniel having a vision in his dream, and it goes along with what Nebuchadnezzar had dreamed. The four beasts are mentioned in the beginning of his dream which is what Nebuchadnezzar had dreamed of, the four empires. It then goes to prophecy over the Messiah and Gods kingdom. The four great beasts are four kings that will rise from the earth, but the Holy people of the most High will receive The kingdom and posesse it forever.
Daniel was troubled by this dream and kept seeking meaning of every detail of it. When we receive a message from God its important to really absorb it in. We may not be meant to understand all of it right away but as we understand more of it a new revelation can take place. Some people have visions while they are awake, some have visions in their sleep. Some may not even realize the dream they had could have been a message from God. God made us all uniquely different, so the way he may communicate with one of us can be different than the next. If one has a hard time quieting their minds when awake, then God may tell you messages in your sleep when your mind is more quiet. Try and be aware of how God gives messages to you, and if you are unsure, pray over it. We wouldnt want messages from God going unnoticed!
Have a very Merry Christmas! And God bless!
