Again, Paul is pointing out the consequence for that saved believer in being overcome with sin in this life; not the next.
2 Peter 3:20 For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning. 21 For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them. 22 But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.
A dog can't return to his vomit in hell. Paul is addressing a carnal believer in how he was before he had gotten saved to the latter end when overcome in this life.
He is still saved as that would be akin to just putting wood, stubble, and hay on that foundation as 1 Corinthians 3:10-17 testifies in verse 15.
He would be the prodigal son that gave up the first inheritance of being that vessel unto honor in His House for wild living into becoming a vessel unto dishonor in His House for not looking to Him for help to depart from iniquity, but he is still son.
Note how “THE LORD WILL JUDGE HIS PEOPLE.” is testifying to that they are still His people.
Also FYI in context, Hebrews 10th chapter's sinning willfully part is about after having the knowledge that there is no more sacrifice for sins. The sin is believing and practicing that believers need another continual sacrifice for sins, thus treating the Son's blood of the New Covenant on par with the blood of goats and bulls that bears repeating.
So basically, those who partake of the Mass and communion thinking they are actually receiving that same one time sacrifice for sins "again" is going to get it, unless they repent, but they are still His people.
The thing is; Paul was warning Galatians that they will not inherit the kingdom of God as vessels unto honor in His House, and be left behind as castaway and thus becoming vessel unto dishonors, BUT they are still in His House. Paul explains this better below.
2 Timothy 2: 18 Who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some. 19 Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, let every one that nameth the name of Christ depart from iniquity. 20 But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour. 21 If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master's use, and prepared unto every good work.
So what is a vessel unto dishonor that is in His House? A saved believer having His seal that did not depart from iniquity, and that includes former believers that have erred from the truth and had their faith overthrown.
The call to depart from iniquity still goes to former believers to go before that throne of grace for help in discernment and wisdom to believe again.
The problem with Judas Isacriot was that he had never believed in the first place.
John 6:64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him. 65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father. 66 From that time many of his disciples went back, and walked no more with him. 67 Then said Jesus unto the twelve, Will ye also go away? 68 Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life. 69 And we believe and are sure that thou art that Christ, the Son of the living God. 70 Jesus answered them, Have not I chosen you twelve, and one of you is a devil? 71 He spake of Judas Iscariot the son of Simon: for he it was that should betray him, being one of the twelve.
It was because of what Simon Peter had said in speaking for the remaining disciples that Jesus pointed out that one of them did not believe in Him and would betray him.
Also; The rest of the disciples were not officially saved until Pentecost when Jesus was no longer present with them but at the right hand of God the Father as a condition for receiving the promise from the Father of the permanent indwelling Holy Ghost as discussed in John 14th chapter.
Concerning Judas.
There are separate requirements to being a Apostle, Bishop and Disciple. All of which would have to be met so that Jesus would not commit a sacrilege of putting a child of Satan in the highest office.
Acts1
20For it is written in the book of Psalms, Let his habitation be desolate, and let no man dwell therein: and his bishoprick let another take.
Acts 1
25to occupy this ministry and apostleship from which Judas turned aside to go to his own place.”
He can't dump it or fall if he never had it. If he never had it why do they even speak of REPLACING Judas when they are not replacing anything at all?
1 Timothy 3
1This
is a true saying, If a man desire the office of a bishop, he desireth a good work.
2A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;
3Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous;
4One that ruleth well his own house, having his children in subjection with all gravity;
5(For if a man know not how to rule his own house, how shall he take care of the church of God?)
6Not a novice, lest being lifted up with pride he fall into the condemnation of the devil.
7Moreover he must have a good report of them which are without; lest he fall into reproach and the snare of the devil.
Judas was INDEED a APOSTLE. Notice below it doesn't say here the names of the Eleven apostles and a TRAITOR.
Matthew 10
2Now the names of the twelve apostles are these; The first, Simon, who is called Peter, and Andrew his brother; James
the son of Zebedee, and John his brother;
3Philip, and Bartholomew; Thomas, and Matthew the publican; James
the son of Alphaeus, and Lebbaeus, whose surname was Thaddaeus;
4Simon the Canaanite, and Judas Iscariot, who also betrayed him.
Judas had the Spirit of HIS FATHER, GOD ALMIGHTY, speak through him.
20For it is not ye that speak, but the Spirit of your Father which speaketh in you.
The apostles are WARNED of things and only those who ENDURE shall be saved.
22And ye shall be hated of all
men for my name's sake: but he that endureth to the end shall be saved.
I wonder if one of them did not endure to the end......
5These twelve Jesus sent forth, and commanded them
Shouldn't it say These Eleven?
Matthew 19
27Then Peter said to Him, “Behold, we have left everything and followed You; what then will there be for us?”
28And Jesus said to them, “Truly I say to you, that you who have followed Me, in the regeneration when the Son of Man will sit on His glorious throne, you also shall sit upon twelve thrones, judging the twelve tribes of Israel.
29“And everyone who has left houses or brothers or sisters or father or mother or children or farms for My name’s sake, will receive many times as much, and will inherit eternal life.
30“But many
who are first will be last; and
the last, first.
Jesus talking to his Eleven, I mean Twelve Apostles. He promises them in the regeneration Eleven, I mean Twelve Thrones.Biggrin
