(1) Show us a passage in the New Testament which demonstrates your ability to (a) judge absolutely, and (b) whether another human is or is not "indwelt by the Holy Ghost."
(2) Show us a passage in the New Testament which demonstrates an example of a practicing fornicator or adulterer who, doing so, is at the same time a regenerated believer-disciple-priest follower of Jesus as Christ and LORD, which is the only valid description of a Christian.
(Compare this to Galatians 5:19-21, which is the Holy Spirit speaking.)
Christians often backslide into “wordly” ways but it doesnt change the fact that they will still end up in Heaven on the day of judgment.
(3) Please find any passage in the New Testament that uses a term translated as "backslider" (noun), or "to backslide" (verb).
(4) Please find a passage upon which to establish the doctrine under which a person claiming eternal spiritual life is permitted to be engaged in the deliberate and unremitting practice of fornication and/or adultery (or any other named sin).
(I think you mean "worldly" here, not "wordly.")
(Compare with 1 John 2:4; 3:6,8 to start)
(5) Tell me which instance of these judgments is the one to which your statement refers, please.:
There are three regarding humans and involving Jesus, The Christ and LORD, as mentioned in the New Testament.
(a) One is the judgment of their sins borne by Him in His body on His Cross-death, for which those who have persistently committed trust in Him and His Faith have received remission.
(b) One is the heavenly judgment by Jesus, The Christ, of the works of resurrected regenerated believer-disciples prior to His return to rule in the earthly sphere.
(c) One is the final judgment of The Christ, the Almighty God to reward the humans who in their physical life rejected Him and His terms of redemption, and remained children and bondslaves of Satan for their willful, unrepentant, and unremitted practice of sin, with eternal death and everlasting torment.
It will be interesting to find out on what authority you presumed to be able to make your statements. Or, if you cannot convince yourself and others, a willingness to take them back. I believe it is very important to make careful distinctions in such a situation, and not to encourage false assumptions.
Gal 5;19-21
19 The acts of the flesh are obvious: sexual immorality, impurity and debauchery; 20 idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions 21 and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
On any given day I and most Christians known to me are guilty of at least one of the above acts of the flesh. Especially “and the like”....
If we back up a few verses and read: 13 You, my brothers and sisters, were called to be free. But do not use your freedom to indulge the flesh[a]; rather, serve one another humbly in love.
We see that the Paul is preaching to “brothers and sisters” and he assumes that they can use freedom to indulge the flesh. He is calling us Christians away from indulging the flesh and replacing this with serving one another humbly in love.
I see scripture and my experience as demonstrating that a Christian is in a constant state of process from indulging the flesh toward serving others as Christ serves. Some Christians may make this process happen in an instant. I think most Christians experience this process over time.
