Father in Heaven.....I come to You on behalf of a precious child who is in the midst of treatment.  A poison that is meant to kill disease is also creating havoc in her body.  The fear, anxiety and physical reactions need Your healing hand, Lord.  Our words and our hopes are for naught.  Our only recourse is to plead the blood of Jesus for the protection and peace of this little child of Yours.  We pray You are hearing our cries and our hopes for a brighter day for her Mother and Grandparents.  Yes, Lord.....we dare pray for a brighter day.....and a healing of her body.  We realize, dear One, that our hope is only in You.  The wisdom of the Medical team is in Your hands too.  Our reliance in the areas of life that we have no education in, lies in the wisdom Doctors and nurses have attained through the efforts of research and development of medicines that will heal.  This reliance is filled with anxious fear, when we are left with the reality of a weeping child, terribly ill and dealing with uncomfortable issues.
Lord, quoting scripture and giving the proverbial platitudes are not what is needed here.   We need to see the scriptural application applied to living and breathing diseased tissue.....scriptural application applied to the pain wracked body.....scriptural application applied to the weariness of the realities.....and above all, the spiritual application to peace that passes all understanding.  As recently written by her wise Grandpa.....He doesn't know what the future holds, but, He knows who holds the future.  The spiritual application of these words are fulfilling in that we can have peace.  Believing and accepting the realities that come our way, dear One, are the only way we can have this peace. 
Jesus, our hope and our prayer is for You to answer us.  We will wait and hope and continue to pray for "what we want to see happen"  (and we truly believe that is okay for us to do).......but, our plea for this peace is simply unwavering......for sweet Lizzie, her mama and all who desperately love her. 
I realize, Lord, that  specifically asking You to fulfill our requests is not selfish.  We are Your children.  We have no one else that could possibly give us an answer......no one but You.
For now, we ask all in the name of Jesus.  Each burden we lay at the foot of the Cross for You to bear.  Amen.
