Romans 16:25 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
26 But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
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.
Mat 24:50 The lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of,
Mat 24:51 And shall cut him asunder, and appoint him his portion with the hypocrites: there shall be weeping and gnashing of teeth.
Mat 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Mat 7:23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Many people devote themselves to Christianity but are not saved.
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,

Gal 5:16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.

Gal 5:24 And they that are Christ's have crucified the flesh with the affections and lusts.
If a person holds on to sin the blood of Christ cannot wash it away.
These people will say they cannot abstain from sin, they are only human, they are not perfect.
So they are holding on to sin.
But they sin on purpose wanting the sin but they could of chose not to sin so what is the excuse.
And if a person hates sin, and does not want sin by the Spirit they can abstain from sin.
If we sin we need to repent and not want it again and allow the Spirit to lead us.
Some people do not come to the truth denying the Spirit to lead them and love sin more than God.
