Pray for Poppop

Please pray for our Poppop, he is in the hospital. Here's our Mama's explanation of what's going on and about the "boo-boos" in his heart" :
After getting a great report about my Dad's heart last week, basically his cardiologist said his heart was all better and didn't need to see him again (Praise God!), he is now at to U of M hospital with his heart in arrhythmia and accelerated heart rate (has been doing this since Sunday- not coincidentally the day he stood up in his church and shared the testimony that his heart was healed). I believe with all my heart that this is an attack on his faith. I did pray over the phone with him yesterday as they drove to the ER and this morning we all went to visit him- Zach & Sydnie really lifted his spirit! Please join me in praying that his faith would increase and that he & my Mom would stand against Satan's attacks on my Dad's body and heart right now. Also that the Doc's would have the mind of Christ and the Lord's wisdom in treating him.
