The bottom line is: we are in intimate relationship with God. It may not always feel like it. There may be moments of doubt. And, we are most free to come and go. Regardless, however, of feelings of emptiness, struggles to believe, and unfaithful goings, our hearts are held by the One who faithfully indwells us.
St Augustine, in his autobiography, testifies to the faithfulness of the Lord:
Late have I loved you, O Beauty ever ancient, ever new, late have I loved you! You were within me, but I was outside, and it was there that I searched for you. In my unloveliness, I plunged into the lovely things which you created. You were with me, but I was not with you. Created things kept me from you; yet if they had not been in you they would not have been at all. You called, you shouted, and you broke through my deafness. You flashed, you shone, and you dispelled my blindness. You breathed your fragrance on me; I drew in breath and now I pant for you. I have tasted you, now I hunger and thirst for more. You touched me, and I burned for your peace.
Yours in Christ,
