As Truth is a person, so is The Way. As surely as any understanding of who He was and what He taught could be expressed, it cannot be understood outside of the person of Who He Is, What He Did and Why He Did It. The Path of Life therefore, as it were, is following Jesus. For the original twelve apostles, this was through both observing who Him directly, as well as by hearing Him teach. Today, while we do not see exactly how He lived the words He preached, we have His Spirit within us to guide us into all truth.
But, most assuredly, His Words are to be obeyed. None of His Words can be fully embraced without the provision of His Spirit, but through Him, and His enabling power, we are able to overcome through faith.
