Sometimes the saints come and find us. I have really felt that in this experience with reading The Interior Castle, that there’s something that Saint Teresa of Ávila is trying to help me to see and interceding for me to see in my relationship with God. It’s a beautiful journey and I feel secure knowing that she's walking with me.
