Oh, man... Frank and Shell are always reaching out to others in Christian Faith... I'm so sorry to hear of this additional challenge...
One ray of hope in this is their faith. I've drawn strength from their testimonies many time and witness to God's love.
May the Lord now wrap them in Grace, peace and find ways to minister to their physical and financial needs during this big time of challenge. Prayers for healing for Frank and their daughter and for Shell to stay strong.
Frank, Shell, keep the Son in your eyes!
