Terry believe me our Heavenly Father will always be there for both of you even in the darkest times. I know this because I have experience it myself. Sometimes it's hard to see it when we are going through it, but later we can see so clearly how God was there with us every step of the way. So please never give up hope or your faith in God. May God give you both the peace that surpasses all understanding, may both of you also feel his loving arms uplifting you as the storm passes by.
Oh Dear Lord hear our prayers and give Marylou the complete healing she so desperately need. May she become a great witness to others who have lost all hope. In Jesus Christ Name I pray, Amen!
I will continue to keep you both in my prayers, it will be easy to remember since I have a friend with the same name as your wife.
