My girlfriend's father is ill. How should I say hello?

Dad: I am thinking of you and silently praying for you: I hope you will recover soon. Your health is my greatest happiness, your happiness is my greatest happiness!

Dad: Being sick is not terrible. As long as faith exists, recovery is not a dream. I will make great achievements in the future. Take disease as a challenge and faith as a weapon. I wish you a speedy recovery!
