This can be seen with the gospel spreading to the Jews throughout Jerusalem and Judea in Acts 1-7, to Samaritans in [[Acts 8]] and to the Gentiles throughout the "rest of the world" in Acts 9-18.
===[[Kerygma]] and Speeches in Acts===
Acts records a number of speeches given by early Christians. In these speeches, the gospel is proclaimed introducing the hearers to Jesus, and appealing for them to believe and become his followers. The content of these initial proclamations is sometimes referred to as [[Kerygma]] (from the [[Koine Greek]] word [[κηρυγμα]] - related to [[κηρυσσω]]).
In total, Acts records 16 speeches, 8 by [[apostle Paul|Paul]], 7 by [[apostle Peter|Peter]] and 1 by [[Stephen]]
There is significant variation in what is actually said in different speeches. All proclaim salvation through [[Jesus Christ]], but each is closely tailored the audience and context.
