Hebrews 10:16-20
Heb 10:16 (KJB)
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;
Here is the great difference between the old covenant and the new covenant. The new covenant would be placed inside the believer and indwelling the believer would be God Himself in the third person of the Triune God, that is, the Holy Spirit. This is why in Hebrews 8:11, the Scripture teaches us that we will not need another to tell us to know the Lord for the inward testimony of the new covenant will cause us to know the Lord. The old covenant had the law of God written upon the tables of stone and required a priest to teach it but the new covenant will be internal and the Holy Spirit will guide us into all truth. (John 16:13 KJV) Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will show you things to come. The old covenant was temporary in nature but the new covenant is eternal in essence. This is why no earthly priesthood can minister the new covenant because only God can impart it to those He has chosen. The new covenant goes from the inside out while the old covenant went from the outside in.
Heb 10:17 (KJB)
And their sins and iniquities will I remember no more.
God once again repeats the great truths from Hebrews 8:12. The sacrifice was so effective in the believerís life, that there is no sin left in the believer. Since Christ has removed the sins from His children, God states that He will remember the sins of the believer no more. True forgiveness includes complete forgetfulness of the sins. See the commentary on Hebrews 10:4 for the listing of the verses which teach that God will blot out and remove our sins forever.
Heb 10:18 (KJB)
Now where remission of these is, there is no more offering for sin.
Remission - Forgiveness or suspension of punishment
This passage concludes the argument concerning sacrifices. Since every sin has been removed from the believer by Christ and they are completely clean before God, there is therefore no more sacrifice for sin. That is, because Christís sacrifice was final in its cleansing of the believer so there would be no need for any more sacrifices. If a person is cleansed of sin, then what would a further sacrifice accomplish? It would accomplish nothing and therefore should not be engaged in. This was in contrast to the Levitical priests who had to continually stand every day and offer sacrifices which could never take away sin bur since Christís sacrifice took away the sin, sacrifices would now cease for they are totally pointless.
Heb 10:19 (KJB)
Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus,
Boldness - Freely, assurance, or fearlessness
Under the old covenant, Israel was forbidden to enter the Holy of Holies. This was reserved for the High Priest once a year and if the High Priest made a mistake, God reserved the right to take his life. The true believer under grace is not under such strictures because the believer is in the Lord Jesus Christ through grace and indwelled by the Holy Spirit and because of these two things we may enter into Godís presence with assurance and confidence that we will be accepted in His holy presence. Under the new covenant, the fear to approach God has been totally removed and replaced with peace. In my own life I have experienced the peace of God when I was praying and the anxiety I had going into Godís presence was melted away and a peaceful assurance took its place. The believer may also enter the presence of God as many times as they want and are not restricted to an annual ceremony or special occasions.
Heb 10:20 (KJB)
By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh;
Hath consecrated - Inaugurated or dedicated
Access to God is no longer through the veil in the tabernacle or temple but now is through the atoning death of the Lord Jesus Christ. Once a year the veil was opened to allow the High Priest to enter into the Holy of Holies. The human nature of Christ, His mortal nature or flesh was the veil which was opened for the true believer to access the Holy of Holies in Heaven. When He physically died upon Calvary, the veil in the temple was torn in two from top to bottom, which signified the end of the Levitical priesthood and the beginning of the High priestly ministry of the Lord Jesus Christ. This access to the Father was consecrated for the true believers that now, full salvation comes through Christ, that is, the removal of all sin from the believer and instant qualification for Heaven.
