You still did not answer the question. How do you know that you are in the truth?
Read the Bible - believe the Bible. Guided by the Holy Spirit who authored the Bible.
How do you know you are born-again? The witness of the Holy Spirit.
So far you have only put forth your own understanding of the Bible
Indeed - I am not accessing another person's "mind" when I post. I am posting what I understand to be true - as you are also doing.
as proof, and then want to blame the Holy Spirit if you are wrong
Nope this is not a "blame game" - this is the path of sola-scriptura testing that Christ demonstrated in Mark 7:6-13. And the told us to follow His example.
The method fully approved in Act 17:11 - sola scriptura testing of all doctrine.
There are many spirits other then the Holy Spirit that will attempt to guide men.
Hence the "Sola scriptura testing" detail above.
The promise of leading into all truth and the gates of hell not prevailing was given to the Church, not to individuals.
Not true as we see in
1 John 2
19 They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, so that it would be evident that they all are not of us.
Individuals choosing -- in the example above, some choose to remain and others to leave.
20 But you have an anointing from the Holy One, and you all know.
Individuals have an anointing from the H.S just as 1 Cor 12 points to this being an individual work. So also does Rom 8:16 show it.
21 I have not written to you because you do not know the truth, but because you do know it, and because no lie is of the truth. 22 Who is the liar except the one who denies that Jesus is the Christ?
Individuals taking one path - vs individuals taking another path in the example above
This is the antichrist, the one who denies the Father and the Son. 23 Whoever denies the Son does not have the Father; the one who confesses the Son has the Father also. 24 As for you, see that what you heard from the beginning remains in you. If what you heard from the beginning remains in you, you also will remain in the Son and in the Father.
Again in the case above individuals choosing - making choices.. no one is 'choosing for them'.
26 These things I have written to you concerning those who are trying to deceive you. 27 And as for you, the anointing which you received from Him remains in you, and you have no need for anyone to teach you; but as His anointing teaches you about all things, and is true and is not a lie, and just as it has taught you, you remain in Him.
In the above case individuals trying to deceive other individuals in the church - and yet the Holy Spirit is with each individual who accepts Him and agrees to accept His guidance.
Arius was as a sola scripturist.
Fine - so was Paul and Luke as we see in Acts 17:11 whee they are approved for using that method
So was Christ in Mark 7:6-13
Same was true of Christ, of Paul, of John in 1 John 2. That did not make them "Wrong"
When you preach the Bible, you are playing it like an instrument
Not true.
. You have an interpretation that you want others to follow.
So do you
How do you known that you are playing the right tune and not in error like Arius? Your eternity depends on it.
Agree with that part - your eternity depends on whether you submit to scripture, to the Word of God - or else setup your own "experience" as the judge of scripture ignoring it as it suits you. It is an important detail to consider.
