sacrifices for sin
I Delight To Do Your Will My God
Psalm 40:6 (KJV) Sacrifice and offering thou didst not desire; mine ears hast thou opened: burnt offering and sin offering hast thou not required.
7 Then said I, Lo, I come: in the volume of the book it is written of me,
8 I delight to do thy will, O my God: yea, thy law is within my heart.
John 4:34 Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work.
Hebrews 10:5 Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:
6 In burnt offerings and sacrifices for sin thou hast had no pleasure.
7 Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.
8 Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law;
9 Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.
10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
The Order of Melchisedek
There is a parallel between Melchizedek and Christ. Melchizedek was a forerunner of Christ.
For this Melchizedek, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him; (KJV) Hebrews 7:1
And Melchizedek king of Salem brought forth bread and wine: and he was the priest of the most high God. Genesis 14:18
Melchizedek is introduced in the Old Testament and reaffirmed in the New Testament.
For every high priest taken from among men is ordained for men in things pertaining to God, that he may offer both gifts and sacrifices for sins: Hebrews 5:1
So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee. Hebrews 5:5
As he saith also in another place, Thou art a priest for ever after the order of Melchizedek. Hebrews 5:6
Jesus is our high priest “that he may offer both gifts and sacrifices for sins.” Jesus was the Lamb slain before the foundation of the world. Jesus himself became the sacrifice for sin.
