Peter was summoned when a female disciple named Tabitha had died in Joppa. Peter went to her location. His prayer was short but powerful. Tabitha came back to life, and many converted when her story became known throughout the area. It is mentioned, possibly because of their unbelief, that Peter put everybody out of the room before he prayed. We may need to consider doing the same in certain situation.
Peter’s prayer for Tabitha
”But Peter put them all forth, and kneeled down, and prayed; and turning him to the body said, Tabitha, arise. And she opened her eyes: and when she saw Peter, she sat up. And he gave her his hand, and lifted her up, and when he had called the saints and widows, presented her alive.” (Acts 9:40-41)
