He was very interested in counselling and soon had a steady stream of people who came seeking his help and understanding. John Uyen was very strong in urging people to more prayer especially before the Blessed Sacrament and for several years formed a group for perpetual adoration of the Blessed Sacrament.Later on, Monsignor Uyen always claimed that he had no head for figures, administration or building and yet he was called upon in God’s own divine providence to rebuild Blessed Sacrament Church after it was devastated by fire in January 1966.
