This Sunday we look at one of the most controversial of all the 150 Psalms in the Bible - Psalm 137. It was the subject of a hit song back in the 70's, but the controversy comes from its strong revenge theme and its call for babies to be smashed against rocks (sounds terrible, right?). So, what are we to make of this Psalm, and others like it that fit into the category known as 'Vengeance Psalms'? Join us on Sunday as Pastor Greg explains how we are to understand this Psalm in light of the Gospel.
