If someone would have told me two years ago that they would be well on their way to becoming Orthodox, I would have laughed ruefully and given a weak smile in return. O ye of little faith.

Keep them in your prayers as they enter their "final leg" of their journey toward the Church. As many of us know, the spiritual warfare only intensifies during this time.
