Acts 28

“Therefore let it be known to you that the salvation of God has been sent to the Gentiles, and they will hear it!” v.28

Read chapter 28
This verse marks a huge chang in history and God's ealing with men.  From this point on salvation is for the nations as well.  Before it was only for the Jews with the exception of a few non-Jews, but now freely available to all.  This verse seems pretty simple how it's translation in most Elgith Bibles but the Greek words carry so much more.  "Salvation," for example, is the Greek word soterion and is a noun which is more fully describes as "salvation-bringing."  Bringing what?  The message of salvation!  Christ already died for and and not it'll be known to all.  This may have started off happening by the spread of John's gospel.  Also the word "sent" is the Greek word apostle which is more than a simple send but a sending with authority and power and a commission.  God's word doesn't return to Him void.  So we see "has been sent" as a post declaration and "will hear it" as a future happening and this is how it should continue to be today.  This ends the Acts of the Apostles and beings a new dispensation of God's dealings with men.  
How have you seen the difference of the dispensation (God's dealings) in the period of the Acts verse to and in the letters in scripture that were written afterwards?  How did/can this verse change your understand of God's dealing with the nations today?
