The most important truth for our interior life is an ever more exact knowledge of the God who dwells in us. His goodness, his providence, his justice, and all his attributes seem to grow beneath our gaze, when we consider them in the light of the mysteries of the Incarnation and Redemption; now we know these only by revelation.

But we receive the greatest light from our knowledge of the Blessed Trinity. There is but one true God. This God who is in us entirely is the God one in nature and three in Persons. This assertion confounds us. This living Trinity, which we are accustomed to represent in I know not what distant heaven where he unveils his splendour for the angels and saints, this adorable Trinity is in us, it lives in us. In me. at this moment, as at all the other instants of my life, God the Father in knowing himself begets his Son and gives to him his whole divine nature so as to make him his equal, consubstantial with himself.
