The nurse who recovered from Ebola had received a blood transfusion from Dr. Kent Brantly, that first American missionary doctor who contracted the disease but survived. So far, he has given about a gallon of his blood to others with the disease, and it seems to be helping. The recipients and the donor must have compatible blood types, but the antibodies that successfully killed the virus in the survivor can be transferred into another person’s body.
I can’t resist the comparison to the blood of Christ. He bore the disease of sin in His body and went so far as to die from it, though that particular virus was ours, not His. But He rose from the dead. Now His blood is our cure. He gives us a blood transfusion:
And he took a cup, and when he had given thanks he gave it to them, saying, “Drink of it, all of you, for this is my blood of the covenant, which is poured out for many for the forgiveness of sins.” (Matthew 26:27-28)
