When God made the human person, he put into him and her a hunger and a thirst that could only be filled up with God. God made us for himself, because he is Love itself and Love must always have an object of that love. As Saint Augustine said well, “You have made us for yourself, O Lord, and our hearts are restless until they rest in you.” The Psalmist also says that today in his words:
As the hind longs for the running waters,
so my soul longs for you, O God.
Athirst is my soul for God, the living God.
When shall I go and behold the face of God?
Given that all people are created with this spiritual hunger, it should not have come as a huge shock to the circumcised believers that many Gentiles were turning to follow Christ. Christ showed us the most perfect way to the Father, the only One who can fill up all the longings of the human heart. Every conversion story is a return of the soul to our God; a filling up of the heart with what it really lacks.
We try to fill up our lives with all kinds of things. We turn on the television to drown out the silence. We seek refuge in food and drink and career and even darker things. But all of this is nothing more than a misguided attempt to fill up our lives with things that do not matter. We can only fill ourselves up with what we truly long for: God himself.
