So you testify you are working out your own salvation with fear and trembling.
Not in the sense you mean, as if it could possibly be in jeopardy. Scripture clearly says that’s a lie. Why? Because it is a lie about who God IS. There is no one greater than Him, and He swore by HIMSELF (see: Hebrews). Salvation is not on me, He bore my sins in Christ.
Those who, like the Jews, pursue it “as if by works” will not obtain it because it is a free gift.
