I’m sorry to hear about your father's health issues. It’s nice of you to ask us to join you in praying for him. I’m praying that God will touch him with His healing hand and bring restoration according to His perfect will. Blessings and peace to you, friend.
Isaiah 53:5 But He was wounded for our transgressions, He was bruised for our iniquities; The chastisement for our peace was upon Him, And by His stripes we are healed.
