There are a few things quite so boring as being religious, but there is nothing quite so exciting as being a Christian! Most folks have never discovered the difference between the one and the other, so that there are those who sincerely try to live a life they do not have, substituting religion for God, Christianity for Christ, and their own noble endeavors for the energy, joy, and power of the Holy Spirit. In the absence of reality, they can only grasp at ritual, stubbornly defending the latter in the absence of the former, lest they be found with neither! They are lamps without oil, cars without gas, and pens without ink, baffled at their own impotence in the absence of all that alone can make man functional; for man was so engineered by God that the presence of the Creator within the creature is indispensable to his humanity. Christ gave Himself for us to give Himself to us! His presence puts God back into the man! He came that we might have life – God’s life!”
