There's not much elaboration needed from my former comments about your "list". For most cases what you have done is misconstrue the condition of the saved with the condition to be saved. Almost all those verses are speaking of the indications one has been saved and not of the conditions to be saved.
Verses you misconstrue in this manner:
... Mt 7:23 Jesus said "I NEVER knew you". As such they had never been saved to begin with
In regards to Matthew 7:23:
Well, the way of having an assurance in knowing the Lord is if a person finds that they are keeping His commandments (1 John 2:3). The person who says they know the Lord, and they do not keep his commandments, they are a liar and the truth is not in them.
So knowing the Lord = Keeping His commandments.
Not knowing the Lord (Whereby Jesus tells a person to depart from Him) = Not keeping His commandments.
Belief Alone Proponents can be broken up into three major groups in regards to sin.
#1. Hardcore Sin and Still Be Saved Type Belief Alone-ism.
#2. Sin in Occasion and Still Be Saved Type Belief Alone-ism (Although I have my doubts about some of those who claim they hold to this position).
#3. Cannot Justify One Sin and You Must Live Holy Type Belief Alone-ism (Although I have my doubts about those who claim to hold to this position).
We both agree that those believers (that you do not like to talk about) who are into Hardcore Sin and Still Be Saved Type Belief Alone-ism (like George Sodini) are not saved because they believe that a Christian can live in gross amounts of sin as a lifestyle all while having a belief alone on Jesus.
Obviously this is a false Antinomianism gospel. We can agree on that. So if a person accepts this gospel in advance knowing full well that they can sin and still be saved (because they went to this church beforehand for years and they know all about how a believer can sin as much as they want and still be saved), and they accept Jesus as their Savior and have a belief alone on him for salvation, it is sure fire bet that they never knew the Lord because they are accepting a false Antinomian gospel.
It is also possible that the Lord and the Holy Spirit did not come into their life to give them a new heart at the receiving of the gospel based on an evil thing that they would do later (like them shortly thereafter learning that they can commit gross amounts of sin with the thinking they can be saved, and so they take joy in all the evil that they are accustomed to doing). In Acts of the Apostles 8:9-24, we learn that the heart of Simon the sorcerer was not right with God because he tried to pay money so as to have the Spirit and the power thereof.
Also, while Matthew 7:23 may refer to believers who have never known the Lord, it does not mean that there are not other passages that teach believers can fall away temporarily into spiritual death and then become alive again spiritually like James 5:19-20, and the Parable of the Prodigal Son (See: Luke 15:11-32, with a special focus on Luke 15:24, and Luke 15:32).
While it is possible that Matthew 7:23 is referring to believers that the Lord had never known the Lord, it may be a statement made by the Lord based on Ezekiel 18:24, too.
"But when the righteous turneth away from his righteousness, and committeth iniquity, and doeth according to all the abominations that the wicked man doeth, shall he live? All his righteousness that he hath done shall not be mentioned: in his trespass that he hath trespassed, and in his sin that he hath sinned, in them shall he die." (Ezekiel 18:24).
Meaning, the Lord no longer remembers the righteousness of a believer who once did righteousness because they have now returned to doing iniquity. According to the verse, all his previous righteousness will not be remembered. Thus it will be as if he never knew him because there are no righteous actions to associate with that person anymore.
1John 2:3-4 "We know that we have come" Again it speaks of behavior as an indicator rather than a cause of salvation.
Jesus is the source of our salvation (1 John 5:12). So knowing or abiding in God is salvation. So the behavior described in 1 John 2:3-4 is showing whether one knows or abides in the Lord who is the source of salvation.
Many Belief Alone Proponents teach that you only lose rewards and fellowship when you sin, but you don't lose your salvation.
But the Bible teaches that believers cannot be out of fellowship with the Lord and be saved.
#1. 1 John 5:12 says He that has the Son has life and He that does not have the Son does not have life. Life is associated with eternal life or salvation.
#2. John 17:3 says eternal life is in knowing the one true God, Jesus Christ. Knowing implies a fellowship. So if you don't know Jesus, then you don't have life (Salvation).
#3. Romans 8:9 says if he a man does not have the Spirit of Christ, he does not belong to him.
#4. Psalms 73:27 says God will destroy all those who abandon Him (or go a whoring from Him).
#5. John 15:6 says if a man does not abide in Him, he is cast forth and burned.
#6. 1 John 1:7 says if we walk in the Light as He is in the Light, the blood of Jesus Christ cleanses us from all sin. Being cleansed of sin is salvation; If you were to contrast this with 1 John 2:4, it says that person who says they know the Lord and does keep His commandments is a liar and the truth is not in them. Revelation 21:8 says all liars will have their part in the Lake of Fire.
#7. Romans 11:21-22 says if you do not continue in his goodness you will be cut off. For if God spared not the natural branches (i.e. the Jews), take heed that he can do the same to you (i.e. Gentile believers). The analogy here is that you are branch and Christ is the tree. We need to continue in Christ's righteousness or goodness, not our own righteousness or goodness, or we will be cut off because of unbelief.
#8. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates? (2 Corinthians 13:5).
In other words, 1 John 2:3 is the fruit of the Lord or proof that a believer knows Jesus and He abides in them. It's the proof in the pudding that they know the Lord and abide in the One (Jesus) who is the source of their eternal life.
The good works they do, or their obedience to God's commands is proof that God lives in them. God is the source of their salvation.
This is why the person who does not keep His commandments and says they know the Lord is a liar, and the truth is not in them. For keeping God's commandments can only be done by the Lord making that to happen through them.
"For it is God which worketh in you both to will and to do of
his good pleasure." (Philippians 2:13).
I will address the rest of what you had written in my next post (Lord willing).
