It's not always possible to control external events. There are so many things that are outside our control: the past, what others think of us, chronic health issues, other peoples' actions, the weather, unforeseen events. This list goes on and on.
It is possible, though, to gain more control over our interior life.
In his book Interior Freedom, Fr. Jacques Phillipe shows us that we possess, each of us, inside of us a space of freedom that no-one can take away. Despite the most unfavorable outward circumstances, we can claim our freedom because God is its source and its guarantee. Without this, we will always be in search for something else to fulfill us, and we will never understand true happiness.
Fr. Philippe lays out a simple but important theme in Interior Freedom: "We gain possession of our interior freedom in proportion to our growth in faith, hope, and love." He explains that the dynamism between these three theological virtues is the heart of our spiritual life, and he underscores the key role of the virtue of hope in our spiritual growth.
