Look at the second part of vs.2 where we hear the Lord say: “This is the one to whom I will look, to the humble and contrite in spirit, who trembles at my word.” This is a great verse to be able to understand how the Lord requires us to be. He calls us to be humble, he calls us to recognize that we have fallen short of the glory of God, he calls us to read and to know the Word of the Lord, and to tremble in front of it because we are convicted.
You can skip ahead to vs.22 if you want. There you will find the promise of a new heaven and a new earth. It will happen on that day that all nations will come before the Lord to worship him. This is a wonderful picture of judgment day. We often think of judgment day as that which is described in vs.15: “The Lord will come in fire…” I prefer to see judgment day as one where we see the Lord and he reaches out to us and embraces us and says well done good and faithful servant, well done. I like that image much more than the fire and the destruction. But…, and this is important, this chapter has both of these pictures. It could be one or the other, or it could be both, depending on who you are.
