All existence and all good that things possess, whether they be of free will or of grace, have been given by the hand of God, who preserves it. Therefore, the soul recognizes that it is more possible to say that God is in them and works good in them than that they themselves do these things. It is not that they do not work, but that they are secondary causes, moved by God, the principal and universal Maker, from whom they have the power to work. Looking at them, the soul does not find value or support in the things themselves, but in the infinite Being that sustains them.
Saint John of Ávila
