In Luke 13:10-21, Jesus performs a healing on the Sabbath, freeing a woman from an eighteen-year disabling spirit, which provokes indignation from the synagogue ruler. He emphasizes that compassion and healing should not be restricted by religious law, likening the kingdom of God to a mustard seed that grows and leaven influencing flour. The passage illustrates the authority of Jesus and the need to recognize and address spiritually crippling influences in our lives.
