If we can lose our salvation by sinning seriously, then how is that NOT saying we get salvation by avoiding sinning (aka, good works, being good, etc.)? In other words, you ARE saying we have to earn, deserve or merit salvation by what we do, or don't do. The "silly idea" is from the false and accursed gospel of Roman Catholicism.
Can you address that instead of mocking sarcasm?
Funny isn’t it.
Christians use the Word of God.
Catholics use strawmen and talking points.
