My younger (and only) brother Paul is a pastor (ordained even!) at Presbyterian Church of New Jersey. Well, one of his kids, Eugene Choi, an 8th grader, re-developed brain cancer! 
Please pray for him and his family (he’s the only son).
Go visit his site and please offer some words of encouragement and much needed prayers…
At such a young age too… but let us remember that God is good all the time.
I find it hard to swallow such sad news usually… so as a self-reminder… Here’s
Psalm 42:5-6
Why are you downcast, O my soul?
Why so disturbed within me?
Put your hope in God,
for I will yet praise him,
my Savior and my God.
My soul is downcast within me;
therefore I will remember you
from the land of the Jordan,
the heights of Hermon—from Mount Mizar.
