I’m sorry to hear about the health issues your sister, Nagamalathi, has been facing. I’m praying that God will touch her with His healing hand and strengthen her according to His perfect will. May He bless your family and provide for all your needs as you look to Him.
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.
