"St. Ignatius believed that our deepest desires are God-given. To long for intimacy with God or others, or to thirst for wisdom, justice, or peace is to encounter God in a very real, utterly human way. It’s good to pray with these desires, but it’s not always easy to pray this way. As we get in touch with our deepest desires, we realize they’re unfulfilled. We feel empty. But in the emptiness is an invitation.

"St. Augustine intuited that God leaves desires unfulfilled for a time so that our longing stretches the capacity of our soul to receive more than we can imagine now. So let’s not rush too quickly from this spot, but enjoy the expectation of the unimaginable fulfillment of our longings that God desires for us." Fr. Kevin O'Brien SJ 

It is in this context that we see why Jesus urges us to persevere in our prayer to the Father. It is not that God does not hear our prayer. But he has something greater and more important to give us, but our capacity to receive it is limited. He calls us to move from what we long for to what he longs for us. This in reality will be greater and better than what we had hoped or desired.
