Eagle, I am sooo sorry to hear this, but hope springs eternal... I know your faith is strong and you won't give up. God is in control and He knows what's best for everyone's soul.
Every day, I pray a prayer called the Divine Mercy chaplet. (If you're interested, PM me and I'll send it to you). It is especially beneficial for the sick. Anyway, here is the last prayer in it:
Eternal God, in whom mercy is ENDLESS, and the treasury of compassion, INEXHAUSTIBLE; look kindly upon us and increase your mercy IN us, that in difficult moments, we might not despair, nor become despondent, but with great confidence, submit ourselves to YOUR Holy Will, which IS love and mercy, itself.
The emphasis is mine, it's just the way I like to pray it, focusing on those key elements.
His Holy Will IS love and mercy itself...
(((HUGS))) for you and your brother.
