"Now we beseech you, brethern, by the
coming of our Lord Jesus Christ, and by
our gathering together unto him, That ye
be not soon shaken in mind, or be troubled,
neither by spirit, nor by word, nor by letter
as from us, as that the day of the Lord is
present," 2 Thessalonians 2:1-2

In the days of the early church, the gospel
made an effect on the pagan world. There
were no Sundays or books about the faith.

The gospel moved across that society, so
that in places like Ephesus, there were big
gatherings of those who opposed it.
