This testimony is from one of our pastors. For months my heart was acting up with arrhythmia and abnormal heart rhythms that would happen every day at least once where my heart would beat above 140 for a while and then stabilize. This was debilitating as it would often happen in the middle of the night and wake me up or happen randomly during the day. This happened for around 9 months straight. I had this condition in the family and learned that the only way to really solve this would be to get surgery and does not go away on its own.
One morning I was spending time with the Lord and heard Him say to me that He was giving me a new heart. From that very moment, I have not had any arrhythmia or heart issues since.
Praise God!
