Wren was diagnosed with PTSD. After several failed medical treatments, he began to search the internet for alternative treatments. He found a man that trains service animals specifically for people with PTSD. This could be the answer he was praying for, at least he hoped so.
Philippians 4:6 (NASB)
Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.
