Professional work — including working in the home, which is a first-class profession — is a witness to the worth of the human creature; a chance to develop one’s own personality; a bond of union with others; a fund of resources; a way of helping in the improvement of the society we live in, and of promoting the progress of the whole human race...
For a Christian, these grand views become even deeper and wider. Because work, which Christ took up as something both redeemed and redeeming, becomes a means, a way of holiness, a specific task which sanctifies and can be sanctified.

Sanctity does not consist in great concerns. — It consists in struggling to ensure that the flame of your supernatural life is never allowed to go out; it consists in letting yourself be burned down to the last shred, serving God in the lowest place… or in the highest: wherever the Lord may call you.

Look, even humanly speaking, it is good not to find it all done for you, with no hitches. Something — a lot! — depends on you. Otherwise, how could you become a saint?
Furrow, 113
When I preach that we have to make ourselves a carpet so that the others may tread softly, I am not simply being poetic: it has to be a reality!
It’s hard, as sanctity is hard; but it’s also easy, because, I insist, sanctity is within everyone’s reach.
