In our study of Isaiah chapter twenty five, we will look at the celebration of the victory of God's people over the schemes of the devil. In chapter 24, we saw that Jesus Christ stepped in and delivered Jerusalem and His people from the hands of Satan and his armies. Usually, with a great victory comes a celebration and parties usually have music. This chapter is essentially the music and it contains three sections of the song that praises God for His hand of deliverance.
"Lord, you are my God; I will exalt you and praise your name, for in perfect faithfulness you have done wonderful things, things planned long ago." NIV translation
This song begins with the acknowledgement that there really only is one God and He is in control. In Hebrew, the "wonderful things" is "pele" which actually speaks of a miracle. In this case, it is talking about the miracle of Jesus Christ stepping in and defeating the armies of the earth that were led by Satan.
We also see that this victory was a part of God's plan from the beginning of time and that He kept His promise to deliver His people.
When delivered from a situation such as the approach of this tremendous army led by Satan, the normal reaction is to celebrate the victory and sing about it.
It was indeed a miracle as there was a huge army attacking Jerusalem and, with a word from His mouth, the army was slain. (see Revelation 19)
"You have made the city a heap of rubble, the fortified town a ruin, the foreigners stronghold a city no more; it will never be rebuilt. Therefore strong peoples will honor you; cities of ruthless nations will revere you." NIV translation
We do not exactly know what specific cities are being talked about here but we can make some educated guesses. They are probably the capitol cities of the nations as well as a chief city that was the headquarters of the world government that was set up and ran by the beast. We do not know the name of this chief city but it will be a city that is completely destroyed by the hand of God. The people from these nations will now be forced to acknowledge the hand of God and the fact that Jerusalem is His chief city.
