Jason,
Emily is indeed in many prayers including mine. There are many "lurkers" here that visit regularly and pray mightily...they just don't feel led to post.
According to His will, may Emily's eye's improve and surgeries become less frequent...If it be His will, let her eyes be miraculously healed that through you and your wife, she will come to know the Power of our Lord God Almighty!
In the interim, may you teach her to "see with the eyes of her heart" and to know Jesus as her personal eyes to the world.
Prayers to for your wife and you. As BH said, it's often way harder on the parents than the kids...as we feel powerless. And we are without Him.
May the Holy Spirit, Christ incarnate, cover you both with loving arms and peace that passes all understanding.
Keep the Son in your eyes!
