This meditation introduces our spiritual preparation for the centenary of Opus Dei, inviting us to rediscover the "freshness" of the early Christians. By reflecting on the need for personal conversion and renewal, we are encouraged to cast off any "stale leaven" of pessimism or routine, opening our hearts instead to the creative responsibility of our charism. As we look towards 2028, let us ask the Holy Spirit to rekindle the gift of God within us, transforming our daily work into a vibrant service of love and a true encounter with Christ.
