The first doctrine is derived from Calvin’s teaching.  The second is a quote from Luther.  St. Paul, plainly, disagrees on both counts.

“Now the works of the flesh are obvious: immorality, impurity, licentiousness, idolatry, sorcery, hatreds, rivalry, jealousy, outbursts of fury, acts of selfishness, dissensions, factions, occasions of envy, drinking bouts, orgies, and the like. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.” (Gal 5:19-21)

“Consequently, brothers, we are not debtors to the flesh, to live according to the flesh. For if you live according to the flesh, you will die, but if by the spirit you put to death the deeds of the body, you will live.” (Rom 8:12-13)

“Do you not know that the unjust will not inherit the kingdom of God? Do not be deceived; neither fornicators nor idolaters nor adulterers nor boy prostitutes nor sodomites nor thieves nor the greedy nor drunkards nor slanderers nor robbers will inherit the kingdom of God.” (1 Cor 6:9-10)

“Immorality or any impurity or greed must not even be mentioned among you, as is fitting among holy ones, no obscenity or silly or suggestive talk, which is out of place, but instead, thanksgiving. Be sure of this, that no immoral or impure or greedy person, that is, an idolater, has any inheritance in the kingdom of Christ and of God.” (Eph 5:3-5)

“I drive my body and train it, for fear that, after having preached to others, I myself should be disqualified.” (1 Cor 9:27)

“So then, my beloved, obedient as you have always been, not only when I am present but all the more now when I am absent, work out your salvation with fear and trembling.” (Phil 2:12)

The correct answer to “Are you saved?”

As the Bible says, I am already saved (Rom. 8:24, Eph. 2:5–8), but I’m also being saved (1 Cor. 1:18, 2 Cor. 2:15, Phil. 2:12), and I have the hope that I will be saved (Rom. 5:9–10, 1 Cor. 3:12–15).  Like the apostle Paul I am working out my salvation in fear and trembling (Phil. 2:12), with hopeful confidence in the promises of Christ (Rom. 5:2, 2 Tim. 2:11–13).
