Paul does not teach that a believer must (dust to dust) die to be saved.
Never said (dust to dust). Why did you add that? Why are you answering your own post instead of mine?
He teaches a believer IS saved once they believe the Gospel.
Saved is a word. What is saved as being?
1 Cor 15:1-4 - nothing about a believer dying to be saved. Eph 2:8-9 as above. Gal 2:16 as above. Rom 3:24-28 as above. Rom 4:5-8 as above. Titus 3:5 as above Eph 1:13 as above.
There is no other way. Salvation is on the other side. There is something you are missing.
