We view it in context of our communion with Jesus, who is the head of His Church. A promise that those who are in communion with, and seek and do the will of Jesus, will manifest the fruit of holiness. An example of Catholic teaching:
"The holiness of many
- One fruit of the conversion brought about by the Gospel is the holiness of so many men and women in our time: not only those whom the Church has officially proclaimed saints, but all those who with simplicity and amid the circumstances of their daily lives testified to their fidelity to Christ. How can one not think of the countless sons and daughters of the Church who throughout Europe’s history have lived lives of generous and authentic holiness in the hiddenness of their family and their professional and social lives? “All of them like ‘living stones’ adhering to Christ ‘the cornerstone’, have built Europe as a spiritual and moral edifice, leaving a most precious inheritance to the future generations. The Lord Jesus promised: 'He who believes in me will also do the works that I do; and greater works than these will he do, because I go to the Father” (Jn 14:12). The saints are living proof of the fulfilment of this promise, and they encourage the belief that this is possible in the most difficult hours of history”. (APOSTOLIC EXHORTATION ECCLESIA IN EUROPA OF HIS HOLINESS POPE JOHN PAUL II, 28 June 2003)
It requires a view of greater being also not the greater as the world views greater. Jesus tells us to pick up our cross and follow Him. The difficult hours of our lives are the crosses we carry. Building the Kingdom of God on earth not done with the bravado of self centered actions, but of sacrifices willingly given with love, charity and fidelity to God.
