The New Covenant: Jesus' Body, Blood, and Promise

Mark 14 brings Jesus down to the last few hours before the cross, and every event matters because the redemptive plan is almost done. Jesus has already sent Judas out, the wheels are already turning, and the eleven still do not really understand what is about to happen.

Passover had been one of the great holy days of Israel, the national memory of deliverance from slavery in Egypt. Numbers 9 shows how important it was, because even ceremonial uncleanness did not simply cancel it. God made provision so that the Passover would still be kept. The meal remembered that God had purchased Israel out of bondage and made them a nation.

Jesus takes that Passover meal and does something completely different with it. The bread becomes the sign of his body, broken for them. The cup becomes the sign of his blood, “the blood of the New Testament,” or the new covenant. The disciples probably had no idea what to do with that language, but Jesus was taking the old symbols of deliverance and making them point to his own sacrifice.

Jeremiah 31 had already promised a new covenant with Israel, not like the covenant made when God brought them out of Egypt. God said that the old covenant had been broken, even though he had been a husband to them. The new covenant would be different. God would write his law in their hearts, forgive their iniquity, and remember their sin no more.

Hebrews shows why that new covenant was necessary. The old covenant had sacrifices, washings, holy days, and commandments, but it could not make the conscience clean. The law required works, but “the law made nothing perfect.” It could purify the flesh in a ceremonial sense, but the blood of bulls and goats could never finally take away sin.

God had always saved by faith. Abraham believed God, and it was counted to him for righteousness. Old Testament saints were saved on credit, so to speak. Their debt had not yet been paid, but God counted them righteous because the payment was certain in Christ.

Christ brings the better covenant because his body and blood actually pay the debt. His sacrifice does not merely cover sin for a time. His blood purges the conscience from dead works to serve the living God. The believer stands before God guiltless, not because guilt never existed, but because the penalty has already been paid. Jesus does it all, and the new covenant rests on his broken body and shed blood.

Key Takeaways

• 1. Passover becomes Christ’s covenant meal. Jesus takes a national memory of deliverance from Egypt and makes it the sign of a deeper deliverance from sin. The bread and cup are not random symbols added to an old ritual. The old meal is gathered up into Christ’s body and blood, because the greater exodus is now at hand. [06:06]
• 2. The law never cleansed conscience. The old covenant could mark a person as ceremonially clean, but it could not remove the inner burden of guilt. Sacrifices and ordinances had real purpose, but they could not make the worshiper perfect “as pertaining to the conscience.” The conscience needed something stronger than repeated animal blood, and Hebrews says that strength is found only in Christ. [33:25]
• 3. Faith received righteousness before Calvary. Abraham’s righteousness did not come from law keeping, because God counted him righteous when he believed. Old Testament obedience flowed from faith, but it did not create righteousness. The debt of sin still waited for the cross, so the saints before Christ were, in that plain but helpful phrase, “saved on credit.” [26:02]
• 4. Christ’s blood pays every debt. The new covenant does not rest on commandments kept well enough, sacrifices offered often enough, or holy days observed carefully enough. It rests on Christ’s body and Christ’s blood. Every sin of every person who belongs to him, past, present, and future, has been paid for by his death. [39:33]
• 5. Clean consciences serve the living God. The blood of Christ does not leave guilt as the believer’s master. God may still lead a person to grieve real sin, but guilt must not govern, consume, or drive the soul. A cleansed conscience is not carelessness about sin, but freedom to come confidently before God and serve him as one already forgiven.

Bible Reading

Mark 14:22-25
“And as they were eating, he took bread, and after blessing it broke it and gave it to them, and said, ‘Take; this is my body.’ And he took a cup, and when he had given thanks he gave it to them, and they all drank of it. And he said to them, ‘This is my blood of the covenant, which is poured out for many. Truly, I say to you, I will not drink again of the fruit of the vine until that day when I drink it new in the kingdom of God.’” [06:06]

Hebrews 9:9-14
“(which is symbolic for the present age). According to this arrangement, gifts and sacrifices are offered that cannot perfect the conscience of the worshiper, but deal only with food and drink and various washings, regulations for the body imposed until the time of reformation. But when Christ appeared as a high priest of the good things that have come, then through the greater and more perfect tent (not made with hands, that is, not of this creation) he entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption. For if the blood of goats and bulls, and the sprinkling of defiled persons with the ashes of a heifer, sanctify for the purification of the flesh, how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God.” [33:25]

Jeremiah 31:31-34
“‘Behold, the days are coming, declares the LORD, when I will make a new covenant with the house of Israel and the house of Judah, not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the LORD. For this is the covenant that I will make with the house of Israel after those days, declares the LORD: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people. And no longer shall each one teach his neighbor and each his brother, saying, “Know the LORD,” for they shall all know me, from the least of them to the greatest, declares the LORD. For I will forgive their iniquity, and I will remember their sin no more.’” [09:25]

Genesis 15:6
“And he believed the LORD, and he counted it to him as righteousness.” [23:24]

Observation questions

1. In Mark 14:22-25, what two familiar Passover elements does Jesus take up, and what does he now call them? [06:06]
2. According to Jeremiah 31:31-34, what are some specific promises that belong to the new covenant, and how are they different from the covenant Israel broke?
3. In Hebrews 9:9-14, what contrast is made between the old sacrifices and the blood of Christ, especially in relation to the conscience? [38:29]
4. What does Genesis 15:6 say happened when Abraham believed the Lord, and what does that show about the way God has always saved? [23:24]

Interpretation questions

1. Jesus turns the Passover meal into a covenant meal centered on himself. What does that suggest about the deeper deliverance he came to accomplish—not just from political slavery, but from sin and judgment? [06:06]
2. Jeremiah says the new covenant includes God writing his law on the heart and remembering sin no more. How do those two promises fit together? Why is inner change connected to full forgiveness? [14:48]
3. Hebrews says the law could not perfect the worshiper “as pertaining to the conscience.” What does that help explain about why repeated sacrifices, holy days, and washings were never enough? [29:40]
4. Abraham was counted righteous by faith before the law was ever given. How does that shape the way a person should understand obedience—whether in the Old Testament or now under Christ? [24:30]

Application questions

1. Many believers know that Christ forgives sin, yet still live under a heavy sense of guilt. Where is guilt most likely to rule the heart right now—past failure, present weakness, or fear of not doing enough—and what would it look like to bring that honestly before God? [36:21]
2. Christ’s blood purifies the conscience “from dead works to serve the living God.” What kinds of dead works are most tempting right now—trying to prove worth, performing for others, religious activity without love, or something else? [38:43]
3. The new covenant rests on Christ’s body and blood, not on keeping enough rules well enough. When does the heart drift back into acting as though acceptance with God depends on performance? [40:46]
4. God has always saved by faith. In daily life, what does believing God actually look like right now—especially in an area where obedience feels costly or unclear? [23:28]
5. A cleansed conscience is meant to free a believer to serve the living God. What would serving God with more freedom and less fear look like this week in the home, at work, or in the church? [39:14]
6. Jesus speaks of drinking the cup new in the kingdom of God. How does that future hope help a believer endure present trouble, disappointment, or weakness? [41:15]
7. God’s people are not meant to be driven by guilt, but led by the Spirit. What helps a person tell the difference between healthy conviction from God and the kind of guilt that only crushes and paralyzes? [41:41]
