"When we think of "Mighty God," power probably comes to mind. The name, the title, "Mighty God" declares that the Messiah of Advent is powerful. So powerful that Isaiah 9 says that the running of the whole world is going to rest on His shoulders. In Isaiah 46:8-10, God is speaking of himself—with attitude:

"Remember this, keep it in mind, take it to heart, you rebels. Remember the former things, those of long ago; For I am God and there is no other; I am God, and there is none like Me. I make known the end from the beginning, from ancient times, what is still to come. I say, 'my purpose will stand, and I will do all that I please.'"

"It is wise and it is good to remember that God is great, and He is powerful, and He way is above us and infinitely far beyond us. And His ways, as Isaiah 55 says, are not our ways."
