The only reason that anyone can be saved is contained in the verse below.
1 Corinthians 2:2
For I determined to know nothing among you except Jesus Christ, and Him crucified.
Everything else mentioned in the scripture is of secondary importance.
Salvation is only available to those that believe in Jesus.
All Paul was actually telling the Corinthians is Christ crucified.
"
For I determined to know nothing among you except..."
Your obedience to Jesus is not the gospel.
Your obedience is not the source of your salvation.
You tell me how someone's obedience has anything to do with Christ's crucifixion?
