There is a mutual inter-causality between deep conversion and deep prayer. They are not merely juxtaposed, one next to the other. Each one helps to bring about the other. The more we are rid of our egocentrisms the more we are opened to the divine infusions of love and intimacy. As Saint Paul puts it, we are transformed from one depth of beauty to another, a gift of the indwelling Spirit (2 Cor 3:18). In the other direction a progressively deepening of prayer furthers our purification from venial sins.
