Jesus calls for absolute obedience. He ends every section of teaching with a call to follow, and consequences if we don’t. That is why the crowd was so amazed, because He taught with authority, calling for absolute obedience. Jesus is God.
If I choose to build my life on my own way or the way of the world, they’re are consequences. Our lives are meant to be fueled by God, there are no substitutes. I can build my life on His teaching, His values, and be strong – because this life is full of storms.
