This meditation celebrates the anniversary of Opus Dei's founding on the Feast of the Guardian Angels, seeing it as a great gift and a precious jewel in the Church. Our vocation is presented as a vibrant, hidden power—a living spring that sanctifies all ordinary realities and professions. We are urged to avoid letting this grace become 'silted up' by sin or distraction, but rather to use all our daily circumstances as means to reach God, living as contemplatives in the world and finding our true being in Him.
