Is this verse the only verse in the NT which addresses the subject of salvation? If there are other verses, and there are, should not the honest inquirer not read every verse which addresses this?
I say most definitely. What do you say? Quite evidently you read verses in isolation and decide what they mean irrespective of what any other verse(s) say.
Should we not read every verse that this writer wrote? This same writer, Paul, also said that 22 categories of wrongdoers have no inheritance in the kingdom of God.
1 Corinthians 6:9-10
Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: [no wrongdoer] neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
Galatians 5:19-21
19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Ephesian 5:5 For this ye know, that [no wrongdoer] no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God.
1 Corinthians 3:17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.
Paul never said that these groups will someday finally have an inheritance. Was Paul lying?
