It does seem that the teachings of the Lord can be severe and demanding. For example, we are to love him over all other things and love even our enemies, and he warns that "whoever causes one of the little children who believe in me to stumble, it would be better for him to have a heavy millstone hung around his neck and be cast into the sea." I believe that Jesus always tells it like it is for our good and we should appreciate that. He reveals to us what we need to know. Without his teachings, we'd easily be lost souls. The truth may not always be pleasing to the ear, but once it penetrates the heart, we are set free.
