okay, but if you show your faith by works, but works don’t prove faith, what proves the faith that saves so you know you aren’t deceived?
This sounds like “heads i win, tails you lose.”
As for all the other things those scriptures cite...i don’t know any pagan totally devoid of all of them, nor any Christian who possesses all of them, so what are they suppose to indicate?
The short answer?
2Co 13:5 Examine yourselves as to whether you are in the faith. Test yourselves. Do you not know yourselves, that Jesus Christ is in you?—unless indeed you are disqualified
That testing is an internal process. For example, I became aware recently that I was guilty of the sin of envy. How did I know? I knew that I had not been made aware of any sins for a while so I asked the Lord to show me my sins, to show me where I'm deficient. Soon after I began to be aware that I had certain negative emotions and thoughts toward certain people and situations. I became aware that this was envy. So now I know that those thoughts and emotions are not normal. They're not to be entertained.
Compare inner life to this list of works of the flesh:
Gal 5:19 Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness,
Gal 5:20 idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies,
Gal 5:21 envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God.
All of us have had or have these to one degree or another. You're in trouble if you think you have none of these to some degree. And you're in trouble if you know you have these but don't care.
1 John is a good book to test yourself:
1Jn 4:20 If someone says, "I love God," and hates his brother, he is a liar; for he who does not love his brother whom he has seen, how can he love God whom he has not seen?
I'm afraid I can really only scratch the surface. At any rate, I want to make clear that you shouldn't go around questioning someone else's salvation. People are on different levels. Someone may have many faults, many sins, but may still be called or are being called. We don't know about others completely so all we can really do is worry about our salvation and try to offer as much help and encouragement as possible to others.
