According to the belief of the Protestant reformation, what is Ephesians 2:8-9, says or mean? Write it in a very very simplify language??

Ephesians 2:8-9 says that we are saved by God's grace through faith, not by anything we do. It means that we can't earn our way into heaven by doing good deeds, but we are saved by believing in Jesus.

Ephesians 2:8-9 says that our salvation is a gift from God, not something we can earn by our own good works. We are saved by God's grace (unmerited favor), through faith in Jesus Christ. This means that we can't boast about our own righteousness because it is God who has given us salvation.
