Prayers Needed for Grandy

Hi everyone, I'd like to ask you to all pray for my Grandy - Jim Zimmerman. He is in the hospital with pneumonia. He's such a healthy guy, so this is quite a shock. He had a cold/fever for about a week and went into the hospital on Friday 7/6. He's very tired and weak and having some trouble breathing. Last night, his blood pressure dropped and they moved him to intensive care. We would appreciate a lot of prayer right now for his pressure to come back up and his body to get back the strength he needs. Thank you!
