I want to give an update. When we called an ambulance, my dad refused to go, and they couldn't make or convince him. The next morning, my dad called with a change of heart and was willing to go! The prayers worked! As
@Orangeredblooded said, God gave him a light to see all those around him and fight. And he did!
My dad has pneumonia and what they referred to as dangerously low potassium. Low to the point that it could have cause cardiac problems, even a heart attack if he waited any longer. He isn't out of the woods yet and has a spot on his lungs they want to look at once they clear the pneumonia. But he's fighting!
I didn't know what else to do the other day but pour my heart out here though tears. I want to thank you all from the bottom of my heart for your prayers and well-wishes! They helped save my dad's life and give him a chance.
