The Greek verb eistrecho is a compound of eis (into) and trecho (to run), meaning to run into or rush inside. It appears only once in the New Testament, describing Rhoda running in with excitement to announce Peter's presence at the gate (Acts 12:14), leaving the door unopened in her joy.
Though rare, this single occurrence carries profound narrative significance. Rhoda's eistrecho — running in with joy rather than opening the door — mirrors the often-absurd human response to answered prayer. The disciples had been praying for Peter's release; when their prayer was answered, they didn't believe it (Acts 12:15). The scene is both humorous and convicting. It illustrates that faith and doubt, prayer and unbelief, can coexist even in devout hearts. The Church's persistent prayer, even amid doubt, was effective — a lesson about the power of communal intercession.
