Although the family finally found work, nonetheless they still lived in poverty. When he was only fourteen, John took a job caring for people in a hospital for those with incurable diseases or who were insane. It was in the midst of this poverty and suffering that John learned to search for beauty and happiness, not in the world, but in God.
St. John eventually became a priest and joined the Carmelite order. This was at the time of great Saint Teresa of Avila, and she asked him to help her in her efforts to reform the Carmelites, who had become very worldly. John supported her belief that the order should return to its life of prayer, but many Carmelites felt threatened by this reform, and some members of John's own order kidnapped him. He was locked in a cell which was only six feet by ten feet, where he was frequently beaten. There was only one tiny window high up near the ceiling. Yet in that unbearable dark, cold, and desolate cell, his love and faith continued to grow. He had nothing left but God - and God brought John his greatest joys in that tiny cell.
After nine months, John escaped. Taking only the mystical poetry he had written in his cell, he climbed out a window using a rope made of strips of blankets. He managed to hide from his pursuers, and from then on his life was devoted to sharing and explaining his experience of God's love.
O God, who didst give to blessed St. John of the Cross, thy Confessor and Doctor, grace to show forth a singular love of perfect self-denial and of bearing thy Cross: grant, we beseech thee; that we cleaving steadfastly to his pattern, may attain to everlasting glory; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee in the unity of the Holy Ghost, ever one God, world without end. Amen.
