1. They shut the door of heaven (13-15)
The Pharisees lived by the tradition of the elders, and they were faithful to follow Jewish culture. But they did not seek God himself through prayerful and obedient Bible study. They branded Jesus as a cult leader and tried to stop people from coming to him. They worked hard to win converts to their way of thinking. Jesus called them sons of hell.
2. Blind guides (16-22)
Jesus calls them 'blind' five times. They are blind because they see everything physically or materially. They have no spiritual sight.
3. Don't neglect important things (23-28)
Justice, mercy and faithfulness are important. The inner man is important. We must clean our hearts and let Jesus reign there. Then we can practice justice, mercy and faithfulness. We must not neglect the important things.
Application: Lord, cleanse my heart and give me spiritual insight.
One Word: Obey God; do the important things
