John 14:23-29 is used to advocate a wide variety of ideas outside the Bible and yet supposedly from God. Jesus taught us to pray to our Father. Some say that the Holy Spirit taught also to pray to Mary. Others claim that the Holy Spirit told them to perform specific tasks which may sometimes seem unwise or of doubtful origin. What exactly will the Holy Spirit teach us? The answer is “all things.” Sometimes we doubt whether or not what someone else claims is indeed from the Holy Spirit. We need patience to wait for the Holy Spirit to lead all of us to come to a common understanding. That may not happen in this life. Notice too that the Holy Spirit will also remind us of the teachings of Jesus. Upon that there is remarkable consensus among Christians.
