The Christian must have a hunger to know. Everything, from the most abstract knowledge to manual techniques, can and should lead to God. For there is no human undertaking which cannot be sanctified, which cannot be an opportunity to sanctify ourselves and to cooperate with God in the sanctification of the people with whom we work. The light of the followers of Jesus Christ should not be hidden in the depths of some valley, but should be placed on the mountain peak, so that “they may see your good works and give glory to your Father in heaven" .
To work in this way is to pray. To study thus is likewise prayer. Research done with this spirit is prayer too. We are always doing the same thing, for everything can be prayer, all activity can and should lead us to God, nourish our intimate dealings with him, from morning to night. Any honourable work can be prayer and all prayerful work is apostolate. In this way the soul develops a unity of life, which is both simple and strong.
We have considered the reality of our christian vocation: how our Lord has entrusted us with the mission of attracting other souls to sanctity, encouraging them to get close to him, to feel united to the Church, to extend the kingdom of God to all hearts. Jesus wants to see us dedicated, faithful, responsive. He wants us to love him. It is his desire that we be holy, very much his own. (Christ is passing by, 10-11)
 Matt 5:16
