The Church of the apostles, in its day, had
a very dynamic miracle-working faith. When
they were thrown into prison, angels of God
released them and sent on to preach again to
the confusion of their enemies. (Acts 5:17-26)

When Paul persecuted the Church (he was
Saul of Tarsus then) who was a mortal enemy.
The church's faith and prayers brought about
his conversion,

When Peter was put in prison and condemned
to death, the prayers of God's people resulted
in the angel of God setting him free.
(Acts 12:3-10)

And when Paul and Silas were cast into prison,
they prayed and sang praises unto God, and
the prison doors were opened by and earthquake.
