In this video I point out that the salvation of the Gentile believers by faith alone in Acts 10:44 is how one is saved.
In Acts 10:44 there are no conditions other then faith for salvation, including confession or prayer.
That is why Romans 10:0-10 and 13 is speaking of temporal salvation, not eternal salvation.
Doctrinally it is a warning to the Jews, just as Acts 2 was, to separate from Judaism and the coming wrath of God on it.
