Psalm 120

We make our dwelling among those who hate the prince of peace. Any place in this world we can find subtle or overt resistence to the name of Jesus.  Every year that God grants us in this life will be another year living among people who hate peace. Because God's peace does not mesh with the desires of this world. God grants peace through submission to him and obedience to his unchanging law. The world seaks peace through the display of power. The former peace is given because Jesus gave up his life, the latter peace must be earned through the taking of the lives of others. The second peace doesn't last; it is based on the ways of this fallen world while the first peace flows from the heart of our creator God and is as eternal as he is.
It didn't take very long to read this song of ascent. I presume that the words were sung repeatedly as the people advanced toward Jerusalem.
