Acts 10 is an important moment in the book of Acts, and in God’s eternal plan (Ephesians 3:1-7).
It’s the moment when God demonstrates that He will accept even uncircumcised Gentiles in Christ, and not just circumcised Jewish people, or people who have converted to Judaism.
The gospel truly is for all, and the blessings in Christ Jesus are offered to everyone in Him (Galatians 3:26-29).
