Receiving the Holy Ghost becomes a reality for those who are willing to obey:
"Him hath God exalted with his right hand to be a Prince and a Saviour, for to give repentance to Israel, and forgiveness of sins.
And we are his witnesses of these things; and so is also the Holy Ghost, whom God hath given to them that obey him." Acts 5:31-32
Many are not willing to obey.
They confess Christ but they have not received the Spirit yet.
Isa 59:1 Behold, the LORD'S hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear:
Isa 59:2 But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear.
2Ti 3:4 lovers of pleasures more than lovers of God;
2Ti 3:5 Having a form of godliness, but denying the power thereof: from such turn away.
2Ti 3:7 Ever learning, and never able to come to the knowledge of the truth.
Some people have a form of living for God but they deny the Spirit leading them because they hold on to sin and are led of the flesh in which they are lovers of pleasures more than lovers of God, and are ever learning and never able to come to the knowledge of the truth that they have to allow the Spirit to lead them and abstain from sin but they believe they are right with God when they hold on to sin.
Gal 5:16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
Gal 5:18 But if ye be led of the Spirit, ye are not under the law.
Gal 5:22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
Gal 5:23 Meekness, temperance: against such there is no law.
Gal 5:24 And they that are Christ's have crucified the flesh with the affections and lusts.
1Co 10:12 Wherefore let him that thinketh he standeth take heed lest he fall.
1Co 10:13 There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.
There is no excuse why a person cannot abstain from sin for a Spirit led life will not fulfill the lust of the flesh for they have crucified the flesh with the affections and lusts.
The people that are led of the Spirit are not under the law because they are not sinning therefore the law cannot touch them for prosecution.
If a person sins they have forfeited repentance and are back under the law until they repent and do not want the sin anymore.
God will not allow a saint to be tempted above what they are able to handle and will give them an escape from the temptation so they can bear it.
So there is no excuse why a person cannot abstain from sin.
But we might sin because we still have a choice but we need to repent of the sin and move forward in the Spirit.
Psa 111:10 The fear of the LORD is the beginning of wisdom: a good understanding have all they that do his commandments: his praise endureth for ever.
Pro 8:13 The fear of the LORD is to hate evil: pride, and arrogancy, and the evil way, and the froward mouth, do I hate.
Mat 10:28 And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
Heb 10:26 For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
Heb 10:27 But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
People who hold on to sin believing they are right with God do not fear Him because they do not depart from evil and God will punish all people that hold on to evil and if they hold on to sin the blood of Christ cannot wash it away because God will not take away a sin they are holding on to.
The Bible says charity, love in action, is greater than faith which John said love not in words, nor in tongue, but in deeds and truth, and faith works by love.
Love is the fulfilling of the law so if we do not have love in action then our faith does not apply in our life.
Paul said charity does not think evil and does not rejoice in iniquity but rejoices in the truth to do good.
If a person holds on to sin then they are not right with God.
