The whole point of the Sermon on the Mount was for Jesus to show the people listening to Him how they could live a life that was pleasing to God, and how they needed a Savior to rescue them from the punishment of death and sin. When you build your life on the teachings of Jesus, you can withstand the storms and the struggles that the world will use to try and knock you down. But if you build your life on the sandy foundation you find in the world, you won’t be able to withstand those storms.
