Luke sets up the sermon by summarizing Jesus' ministry activity (4:14-15, 31-32, 40-41). Jesus ministers on a plain. The term topu pedinou refers to a level place, but can refer to a plateau area in mountainous terrain (Mt 14:23 compared to 15:29; Is 13:2 LXX; Jer 21:13 LXX). Beyond this no specific locale is given. Jesus' ministry reflects the compassion and love he claims God has for humanity. So he heals people of disease and exorcises demons. The text emphasizes the power that proceeds from him. Whether they are apostles, disciples or part of the crowd, all sorts of people receive Jesus' ministry. Jesus' teaching and ministry extends beyond insiders. He attempts to reach those outside his new community.
