I am sorry to hear your daughter is also sick with this illness.
I pray that God in the name of Jesus will decide to heal her also.
And that she will know the peace that surpasses all understanding- as she awaits His will. I pray that she will be delivered in every way. That she will be filled with joy. Only with God are all things possible.
Also that you will receive more grace than ever in this difficult situation.
That You will all know His comfort and love as you live from day to day.
