Then he told them to get a whole bunch of sticks and tie them together and then try to break it. They could not. Then he would say to them that that bunch of sticks is family. A person by themselves is easily broken, but together we are strong. We are the family of God - we have a bond stronger than blood and will last longer.
Blood ties end at death.
Jesus teaches us that even marriage ends at death. But our spiritual ties as brothers and sisters in Christ will last throughout eternity. We can weather any storm if we stick together. Reach out for help in the time of storm in your life. Do not use the lifeboat and try to run away from your problem like the sailors were going to do in the story.
