Heavenly Father, most Awesome and Mighty God, I pray that you uplift this man and his family. I pray for fast healing of his son. I pray they find what's causing his medical problems quickly. Abba, I claim your promise in
Matthew 7:7-8
7 Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you:

8 For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.

I pray this in Yeshua Hamashiach's name, Amein!
