God had miraculously released Peter from prison (Acts 12:6-10).  It all happened so quickly that he had little time to take it all in.  But by the time the apostle was walking through the silent dark streets of Jerusalem, he realised what the Lord had done for him.  The Lord's intervention was not just a personal relief; it was a manifestation of His power in frustrating the murderous ambitions of King Herod and the religious leaders.  Then he went to Mary's house where the church people were meeting.

It was a large merchant's property with an outer gate and courtyard leading to the house; and they had servants.  The believers were still there as they had been praying through the night (Acts 12:5).  Peter banged on the outer gate and a servant girl came to hear what the noise was about.  Peter identified himself and Rhoda recognised his voice.  Nevertheless, because of the security risk she did not unlock the gate but ran to tell her employer and the group of praying believers that Peter was outside.

Their reaction seems comical.  Although they had been praying for Peter's release, they could not believe that their prayer was answered.  Instead, they accused the servant of being deluded and hearing voices that did not exist.  The more Rhoda insisted that it really was Peter, the believers refused to believe but tried to pacify her by saying that the voice came from Peter's 'angel' (Matthew 18:10).  They had no idea that Peter had just encountered a real angel who had released him from prison at God's command and in answer to their prayers.

We may think that disbelief lodges only with unbelievers.  This narrative shows us that even believers in Jesus can fail to receive God's answers to their prayers.  They may be so overcome by their sorrow that they either fail to pray or fail to watch for the answer (Mark 14:37-38).  Their problem seems so hopeless that they fail to trust the Lord.  Their praying is more a cry of despair than an anticipation of divine intervention; and the Evil One would like us to be so trapped by fear that we cannot exercise faith.  And yet, God is gracious and amazingly often answers prayer despite our faithlessness (Mark 4:38-41).  Nevertheless, we should take a rebuke from this passage.  Let us ask for His help to pray with the full expectation that He will answer and that we will glorify Him by recognising what He has done (Psalm 17:6).
