You can't always see it

Real spirituality and spiritual growth, however, have to be distinguished from religious activities and pious exercises. These exercises merely mimic spirituality. Unfortunately, many people think that they grow close to God by performing religious practices and doing religious things. That is not spirituality. They may even get a reputation for being pious. Jesus lived for thirty years in Nazareth, and you would think the townsfolk He grew up with would have been impressed with His holiness. Oddly enough, they were surprised when He began His public mission and began to preach the Good News. “Where did he get all this from? Isn’t this the carpenter’s son?” Obviously, His holiness didn’t make a big impression. You might wonder how Jesus could have kept His exquisite spirituality hidden during all those years, so that even His playmates were shocked by His apparent newfound interest in religion. What made it possible for Jesus to keep His spiritual life hidden from the eyes of those who lived so close to Him was that His holiness was genuine. It did not de- pend on showy external practices.— Never Alone, 13
