I think you focus too much focus on reasons and limits for people not to have the spirit.
Luke 1
41When Elizabeth heard Mary’s greeting, the baby leaped in her womb; and Elizabeth was filled with the Holy Spirit.
42And she cried out with a loud voice and said, “Blessed
are you among women, and blessed
is the fruit of your womb!
43“And how has it
happened to me, that the mother of my Lord would come to me?
44“For behold, when the sound of your greeting reached my ears, the baby leaped in my womb for joy.
All Mary had to do is say "HI".
And Elizabeth was filled with the Holy Spirit.
We see with Jesus and Stephen mercy directed to people who are direct enemies, for anyone to receive any desire of mercy is itself a grace. There is no qualification for it.
Paul was hunting down Christians, he's already far along to rejecting he says he was in blasphemy.
But Jesus intervenes.
In his own testimony he not only is disqualified he considered part of the reason he was saved so undeserving was to express just how great the patience and mercy of God was.
1 timothy 1
13Even though I was once a blasphemer and a persecutor and a violent man, I was shown mercy because I acted in ignorance and unbelief.
14The grace of our Lord was poured out on me abundantly, along with the faith and love that are in Christ Jesus.
15Here is a trustworthy saying that deserves full acceptance: Christ Jesus came into the world to save sinners—of whom I am the worst.
16But for that very reason I was shown mercy so that in me, the worst of sinners, Christ Jesus might display his immense patience as an example for those who would believe in him and receive eternal life.
Its his actually being evil and ignorant which motivates grace to show up.
Romans 5
20Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound:
21That as sin hath reigned unto death, even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord.
Of course that doesn't mean go be evil and ignorant so grace of God shows up.
Romans 6
1What shall we say then? Shall we continue in sin, that grace may abound?
2God forbid. How shall we, that are dead to sin, live any longer therein?
Doctor is for the sick.
Same time its not just a Chain-Letter gospel, Its not something preached only on the sake of being preached.
Romans 2
13for
it is not the hearers of the Law
who are just before God, but the doers of the Law will be justified.
James 2
22But be ye doers of the word, and not hearers only, deceiving your own selves.
23For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass:
24For he beholdeth himself, and goeth his way, and straightway forgetteth what manner of man he was.
25But whoso looketh into the perfect law of liberty, and continueth
therein, he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.
26If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion
is vain.
27Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction,
and to keep himself unspotted from the world.
The only way to preach the whole gospel is to do it. Saying it is just half the gospel.
