<p>12:15 <i>And they said to her: You are mad<em>- </em></i>The believers gathered together to hold a prayer meeting for Peter&rsquo;s release. Their prayers were answered; he stood outside, knocking on the door. But they simply didn&rsquo;t believe it. They couldn&rsquo;t conceive their prayer was answered. They mocked poor Rhoda and told her to go back and watch the door and not disturb them any more while they prayed for Peter&rsquo;s release. And having mocked her, they got back on their knees and asked again for his release. We can pray, in faith apparently, but with no very deep faith that the answer in actual reality will happen or may already have been granted.</p><p><i>But she confidently affirmed that it was so</i>- The only other time this Greek word occurs is again in Luke's writing, when describing how the girl in the courtyard confidently affirmed that Peter was Peter (Lk. 22:59). For me, this clinches the identity of that girl with Rhoda; see on :13 <em>Rhoda</em>.</p><p><em>And they said: It is his angel</em>- The early church clearly believed in the Biblical concept of guardian Angels who represent us and can therefore be understood to appear as us before the court of Heaven.</p>
