Sin is the willful disobedience of the law of Yah, which actually separates us from Him, because sin cannot exist in his presence.
This is why there was a veil in the temple, but once Yahushua gave Himself as the perfect and final sacrifice offering, that veil was torn in two, from top to bottom, signifying there is nothing that stands in between us and our Father, when we are covered by the perfect sacrifice that was poured upon the mercy seat.
You might ask how was the blood really put on the mercy seat of the ark when it had been seen over 600 years, but as always, our Father had it all planned. That ark was approximately 20 feet below the crucifixion site at Calgary, and when the earth shook, and the rocks were cracked, His blood flowed down and onto the mercy seat through the crack in the rock that was called place of a skull.
All that is a mere shadow or type. The blood cleanses us not because it literally touched a physical ark but rather it cleanses because it is what establishes the New Covenant which is something we must enter into.
Heb 9:14 How much more shall
the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
Heb 9:15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
Heb 9:16 For
where a testament is, there must also of necessity be the death of the testator.
Heb 9:17 For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.
Heb 9:18 Whereupon neither the first testament was dedicated without blood.
Heb 9:19 For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and of goats, with water, and scarlet wool, and hyssop, and sprinkled both the book, and all the people,
Heb 9:20 Saying,
This is the blood of the testament which God hath enjoined unto you.
Heb 9:21 Moreover he sprinkled with blood both the tabernacle, and all the vessels of the ministry.
Heb 9:22 And almost all things are by the law purged with blood; and without shedding of blood is no remission.
Heb 9:23 It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these.
Heb 9:24 For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us:
Heb 9:25 Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others;
Heb 9:26 For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.
Jesus is the mediator of the reconciliation process between the repentant sinner and God the Creator. The Bible says...
Heb 10:16 This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
Heb 10:17 And their sins and iniquities will I remember no more.
Heb 10:18 Now where remission of these is, there is no more offering for sin.
Heb 10:19 Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus,
Heb 10:20 By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh;
Heb 10:21 And having an high priest over the house of God;
Heb 10:22 Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.
Heb 10:23 Let us hold fast the profession of our faith without wavering; (for he is faithful that promised
Heb 10:24 And let us consider one another to provoke unto love and to good works:
Heb 10:25 Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
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.
Heb 10:28 He that despised Moses' law died without mercy under two or three witnesses:
Heb 10:29 Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?
Notice...
1. We approach God in a new and living way (grace which reforms the heart as opposed to law which only reforms outer conduct).
2. We approach God via the blood with a true heart (godly sorrow working repentance produces an honest confession of past wrong doing).
3. Our past rebellion is cleansed.
4. Future rebellion is to hold the reconciliation process in contempt, it is to treat the blood of Jesus as cheap.
Hence Paul taught...
2Co 5:17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
2Co 5:18 And all things are of God,
who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation;
2Co 5:19 To wit, that
God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
2Co 5:20
Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ's stead, be ye reconciled to God.
2Co 5:21
For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
2Co 6:1 We then, as workers together with him, beseech you also that ye receive not the grace of God in vain.
The reconciliation process deals with the human heart and effects a complete purging of iniquity. Thus we are removed from the state of "sinning unto death" and thus God may forgive us without issuing a license to sin.
