I have reserved to myself 144,000 who will not bow to the image

As far as the nature of Christ goes, and how we coincide.  Christ was "Born again of the Holy Spirit from the womb" 

Those who are born again do not sin willfully or knowingly

.

1Jo 3:6 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.

Here is where the problem lies.  People say "I'm born again".  Yet they still are willfully sinning are they truly born again according to the words of God through his prophets.  Lets see:

Joh 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. Joh 3:6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. Joh 3:7 Marvel not that I said unto thee, Ye must be born again.

NOTE:  Jesus said those who are spirit are spirit and those who are flesh are flesh.  Did Paul agree with this? 

Rom 7:5 For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death.

Notice all the past tense.  Not that we are not in a sinful body we are obviously.[Romans 8:3] But our spirit has been born again and no longer do we have a carnal mind.  We have the mind of Christ.  The son of God condemned sin in the flesh.  The carnal mind hates God. [Rom 8:7].  We do not have sinless flesh.  But the flesh is not the ruler in this body.  Christ dwells in us and in this we keep the commandments because “this is love that we keep his commandments”[1 John 5:3].  Who is ruler of this temple?  Is this the temple of the Holy Spirit?  Or is there an evil spirit that still lives in this house?

Rom 8:4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.Rom 8:8 So then they that are in the flesh cannot please God. Rom 8:9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. Rom 8:10 And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.

Gal 5:24 And they that are Christ's have crucified the flesh with the affections and lusts.Gal 5:25 If we live in the Spirit, let us also walk in the Spirit.

Those words agree with Christ "That which is born of flesh is flesh, that which is spirit is spirit" So Paul and Christ agree as one.  When Paul said that which I want to do I can’t, Paul was referring to when he didn’t have the spirit of God and tried to keep the law with a carnal mind.  [Romans 7:5,14,18] Does Peter still commit sin after being born again?

1Pe 1:22 Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently: 1Pe 1:23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth forever.

Peter's testimony is he is born of Spirit as well so he agrees with Christ who was conceived by the Holy Spirit from the womb.  So we get the Holy Spirit at Baptism. [Acts 2:38, Romans 6] and die to sin.  After this walking by faith.  Alot of people don't have faith so they go in the water sinners and come out of the water sinners.  That is not the meaning of Baptism.  That is not the meaning of being born again.  Here is what Ellen White said about those who were to be baptized into the body of Christ.

The principles of righteousness must be implanted in the soul. The faith must grasp the power of Jesus Christ, else there is no safety. Licentious practices are getting to be as common as in the days before the flood. Not one should be buried with Christ by baptism unless they are critically examined whether they have ceased to sin, whether they have fixed moral principles, whether they know what sin is, whether they have moral defilement which God abhors. Find out by close questioning if these persons are really ceasing to sin, if with David they can say, I hate sin with a perfect hatred.--Letter 26d, 1887, p. 6. (To "Brother Covert and those who hold responsible positions in the Indiana Conference," September 27, 1887.

So when we are Born again[Born of spirit] we have cease to sin just as Jesus was Born again[Born of Spirit] from the womb.  But please notice that these persons are still ceasing to sin in this quote as it is obvious that a new baby Christian does not have all knowledge.  He must grow in the power of God.  Gods power will keep him from falling back into old sins if he trusts him. 

This is righteousness by faith[The victory].  Something the General Conference of Seventh Day Adventists rejected in 1888. 

1Jo 3:9 Whosoever is born of God[born again of the spirit] doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.

1Jo 5:4 For whatsoever is born of God[born again of the spirit] overcometh the world: and this is the victory that overcometh the world, even our faith.

1Jo 5:18 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not. 1Jo 5:19 And we know that we are of God, and the whole world lieth in wickedness.1Jo 5:20 And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.

The 144,000 have this message.  We are to know and believe and in this we do know the children of God and the children of the devil.   

1Jo 3:7 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous

If it were so possible even the very elect would be decieved.  Let no man decieve you.  You will know them by there fruits.  A good tree does not bring forth bad fruit.
