5 So Peter was kept in prison, but earnest prayer for him was made to God by the church.
“So Peter was kept in prison, but earnest prayer for him was made” – The context and actions of Herod described in verses 1-4, seem like certain death for Peter. In moments of difficulty (no matter the intensity of the difficulty), believers should turn to God for both hope and answers. ”casting all your anxieties on him, because he cares for you.” 1 Pe 5:7.
“earnest prayer” – pertaining to an unceasing activity, normally involving a degree of intensity and/or perseverance—‘without ceasing, continuously, constantly.’ Johannes P. Louw and Eugene Albert Nida, Greek-English Lexicon of the New Testament: Based on Semantic Domains (New York: United Bible Societies, 1996), 655.
