Jesus' triumphant entry was shortly followed by his passion. The centurion suddenly believed in Jesus even if he witnessed the latter's gruesome and ugly fate in the hands of the Jews. We enter all sorts if relationships and enterprise with much joy but later we were confronted with pain and difficulties. It's a call to commitment. Ugliness and imperfections at times inspire. [Mark 14:1-15:47, Palm Sunday of the Lord's Passion]
