Sandy,

Be anxious for nothing, but in everything by prayer and supplication with
thanksgiving let your requests be made known to God. And the peace of God,
which surpasses all comprehension, will guard your hearts and your minds in
Christ Jesus. Finally, brethren, whatever is true, whatever is honorable,
whatever is right, whatever is pure, whatever is lovely, whatever is of
good repute, if there is any excellence and if anything worthy of praise,
dwell on these things.

Testing, no matter how difficult in the short term,  is a small price to
pay for confirmation of excellent health in the long term.

Praying for you.

Brad
