When we have no mediator, then the purification by Christ's blood/righteousness will stop.

Do you believe you can become so perfect that you no longer need the righteousness of Christ to enable you to stand before a Holy God?

PS - Arnold, I can't help but believing I have misunderstood you. Are you saying "whosoever abideth in him sinneth not . . . whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God" must be taken to mean they continue to sin therefore they continue to repent?

Christ's death was required even for sins done ignorantly.

Said the angel, "If light comes, and that light is set aside, or rejected, then comes condemnation and the frown of God; but before the light comes there is no sin, for there is no light for them to reject.("Spiritual Gifts Volume 4b, page 3)

Says the prophet: "Who may abide the day of His coming? and who shall stand when He appeareth? for He is like a refiner's fire, and like fullers' soap: and He shall sit as a refiner and purifier of silver: and He shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the Lord an offering in righteousness." Malachi 3:2, 3. Those who are living upon the earth when the intercession of Christ shall cease in the sanctuary above are to stand in the sight of a holy God without a mediator. Their robes must be spotless, their characters must be purified from sin by the blood of sprinkling. Through the grace of God and their own diligent effort they must be conquerors in the battle with evil. While the investigative judgment is going forward in heaven, while the sins of penitent believers are being removed from the sanctuary, there is to be a special work of purification, of putting away of sin, among God's people upon earth. This work is more clearly presented in the messages of Revelation 14.(GC 425)

M: Is "stained with sin" the same thing as sinning? That is, are they guilty of sinning? For example, are they guilty of sinning each time they confess a sin?

R: Their obedience (as everything else which comes from sinners) is imperfect, tainted with sin, and cannot be accepted by God without the merits of Christ's blood.

"When it is in the heart to obey God, when efforts are put forth to this end, Jesus accepts this disposition and effort as man's best service, and He makes up for the deficiency with His own divine merit." {FW 50.1}

M: Arnold, I can't help but believing I have misunderstood you. Are you saying "whosoever abideth in him sinneth not . . . whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God" must be taken to mean they continue to sin therefore they continue to repent?

A: That verse means that there is a class of sin that those born of God do not and cannot commit. However, 1Jn 1:8 means that there is a class of sin that we cannot deny that we have. Later in the book, John mentions a class of sin that does not lead to death.

Look in the sanctuary system, as GC has started already, and you'll see different ways of addressing the different classes of sin. Almost every sacrifice is for a sin done ignorantly, but the sinner offers the sacrifice when he finds out about the sin. Christ's death was required even for sins done ignorantly.

However, there was a sacrifice that was not attached to a specific sin. As we know, confession and repentance should be specific. But the morning and evening sacrifices were not for any specific sin. Yet, the sacrifice still typified Christ's death for sin.

Sins done in ignorance, once discovered, required specific sacrifices, confession and repentance. What sins were the morning and evening sacrifices for? What sins were confessed upon the animal? I believe these sacrifices were for ignorant sins that were not yet discovered.

When did the morning and evening sacrifices stop?

We may have the peace which passeth understanding; but it will cost us battles with the powers of darkness, struggles severe against selfishness and inbred sin. The victories gained daily through persevering, untiring effort in well-doing will be precious through Christ who has loved us, who gave Himself for us, that He might redeem us from all iniquity, and purify unto Himself a "peculiar people, zealous of good works." . . . {LHU 98.5}

"If any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new." 2 Corinthians 5:17. Through the power of Christ, men and women have broken the chains of sinful habit. They have renounced selfishness. The profane have become reverent, the drunken sober, the profligate pure. Souls that have borne the likeness of Satan have become transformed into the image of God. This change is in itself the miracle of miracles. A change wrought by the Word, it is one of the deepest mysteries of the Word. We cannot understand it; we can only believe, as declared by the Scriptures, it is "Christ in you, the hope of glory." {AA 476.1}

When the Spirit of God controls mind and heart, the converted soul breaks forth into a new song; for he realizes that in his experience the promise of God has been fulfilled, that his transgression has been forgiven, his sin covered. He has exercised repentance toward God for the violation of the divine law, and faith toward Christ, who died for man's justification. "Being justified by faith," he has "peace with God through our Lord Jesus Christ." Romans 5:1. {AA 476.2}

But because this experience is his, the Christian is not therefore to fold his hands, content with that which has been accomplished for him. He who has determined to enter the spiritual kingdom will find that all the powers and passions of unregenerate nature, backed by the forces of the kingdom of darkness, are arrayed against him. Each day he must renew his consecration, each day do battle with evil. Old habits, hereditary tendencies to wrong, will strive for the mastery, and against these he is to be ever on guard, striving in Christ's strength for victory. {AA 476.3}

First of all, I do not think discussing the timing of putting on incorruption as it relates to "righteousness and true holiness" is off topic. Thank you for bringing it up. I agree with Tom, though, that "righteousness and true holiness" cease requiring the atoning blood of Jesus before they put on incorruption.
