But, as Christians, we are called to convert our loneliness into solitude. We are called to experience our aloneness not as a wound but as a gift — as God’s gift — so that in our aloneness we might discover how deeply we are loved by God.
It is precisely where we are most alone, most unique, most ourselves, that God is closest to us. That is where we experience God as the divine, loving Father, who knows us better than we know ourselves.
Solitude is the way in which we grow into the realization that where we are most alone, we are most loved by God. It is a quality of heart, an inner quality that helps us to accept our aloneness lovingly, as a gift from God.
