Lamentations 3, 4 and 5 continues the lament over what has happened to the people of God. It acknowledges that God does not want to punish His people but is forced to do it because they continue in their sin. As time goes on it seems as though God will never save them. They have been brought low completely. Only then might they ask for help.
John 20 tells of Jesus’ encounters with his disciples after his resurrection. First he appears to Mary Magdalene. She recognizes him immediately. Next he appears to the disciples who are hiding away from the Jews. He breathes on them to give them the peace of his Holy Spirit. Thomas is not there and doesn’t believe that Jesus has really risen. Jesus appears to Thomas, who then believes. Jesus blesses those of us who believe even though we have not seen.
