The SIGNS of the Covenants

Regarding God's covenant with Noah and all of the living things which had accompanied him on the ark, we read:

Then God said to Noah and to his sons with him, “Behold, I establish my covenant with you and your offspring after you, and with every living creature that is with you, the birds, the livestock, and every beast of the earth with you, as many as came out of the ark; it is for every beast of the earth. I establish my covenant with you, that never again shall all flesh be cut off by the waters of the flood, and never again shall there be a flood to destroy the earth.” And God said, “This is the sign of the covenant that I make between me and you and every living creature that is with you, for all future generations: I have set my bow in the cloud, and it shall be a sign of the covenant between me and the earth. When I bring clouds over the earth and the bow is seen in the clouds, I will remember my covenant that is between me and you and every living creature of all flesh. And the waters shall never again become a flood to destroy all flesh. When the bow is in the clouds, I will see it and remember the everlasting covenant between God and every living creature of all flesh that is on the earth.” God said to Noah, “This is the sign of the covenant that I have established between me and all flesh that is on the earth.” (Genesis 9:8-17, ESV)

Regarding God's covenant with Abraham and his descendants, we read:

"And God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations. This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised. You shall be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between me and you. He who is eight days old among you shall be circumcised. Every male throughout your generations, whether born in your house or bought with your money from any foreigner who is not of your offspring, both he who is born in your house and he who is bought with your money, shall surely be circumcised. So shall my covenant be in your flesh an everlasting covenant. Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.” (Genesis 17:9-14, ESV)

Regarding God's covenant with the people of Israel, we read:

"The Lord then gave these instructions to Moses: “Tell the people of Israel: ‘Be careful to keep my Sabbath day, for the Sabbath is a sign of the covenant between me and you from generation to generation. It is given so you may know that I am the Lord, who makes you holy. You must keep the Sabbath day, for it is a holy day for you. Anyone who desecrates it must be put to death; anyone who works on that day will be cut off from the community. You have six days each week for your ordinary work, but the seventh day must be a Sabbath day of complete rest, a holy day dedicated to the Lord. Anyone who works on the Sabbath must be put to death. The people of Israel must keep the Sabbath day by observing it from generation to generation. This is a covenant obligation for all time. It is a permanent sign of my covenant with the people of Israel. For in six days the Lord made heaven and earth, but on the seventh day he stopped working and was refreshed." (Exodus 31:12-17, ESV)

Regarding God's covenant with King David, we read:

Hear then, O house of David! Is it too little for you to weary men, that you weary my God also? Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel. (Isaiah 7:13-14)

For to us a child is born, to us a son is given; and the government shall be upon his shoulder, and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. Of the increase of his government and of peace there will be no end, on the throne of David and over his kingdom, to establish it and to uphold it with justice and with righteousness from this time forth and forevermore. The zeal of the Lord of hosts will do this. (Isaiah 9:6-7)

There shall come forth a shoot from the stump of Jesse, and a branch from his roots shall bear fruit. And the Spirit of the Lord shall rest upon him, the Spirit of wisdom and understanding, the Spirit of counsel and might, the Spirit of knowledge and the fear of the Lord. And his delight shall be in the fear of the Lord. He shall not judge by what his eyes see, or decide disputes by what his ears hear, but with righteousness he shall judge the poor, and decide with equity for the meek of the earth; and he shall strike the earth with the rod of his mouth, and with the breath of his lips he shall kill the wicked. Righteousness shall be the belt of his waist, and faithfulness the belt of his loins... In that day the root of Jesse, who shall stand as a signal for the peoples—of him shall the nations inquire, and his resting place shall be glorious. (Isaiah 11:1-5, 10, ESV)

Regarding the New Covenant through Jesus Christ, we read:

Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit. And her husband Joseph, being a just man and unwilling to put her to shame, resolved to divorce her quietly. But as he considered these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.” All this took place to fulfill what the Lord had spoken by the prophet: “Behold, the virgin shall conceive and bear a son, and they shall call his name Immanuel” (Matthew 1:18-23, ESV)

In the sixth month the angel Gabriel was sent from God to a city of Galilee named Nazareth, to a virgin betrothed to a man whose name was Joseph, of the house of David. And the virgin's name was Mary...And the angel said to her, “Do not be afraid, Mary, for you have found favor with God. And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. He will be great and will be called the Son of the Most High. And the Lord God will give to him the throne of his father David, and he will reign over the house of Jacob forever, and of his kingdom there will be no end. (Luke 1:27, 30-33, ESV)

And in the same region there were shepherds out in the field, keeping watch over their flock by night. And an angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were filled with great fear. And the angel said to them, “Fear not, for behold, I bring you good news of great joy that will be for all the people. For unto you is born this day in the city of David a Savior, who is Christ the Lord. And this will be a sign for you: you will find a baby wrapped in swaddling cloths and lying in a manger. (Luke 2:8-12)

Regarding the people of Christ's day demanding a sign that he was indeed the promised Messiah, we read:

Then some of the scribes and Pharisees answered him, saying, “Teacher, we wish to see a sign from you.” But he answered them, “An evil and adulterous generation seeks for a sign, but no sign will be given to it except the sign of the prophet Jonah. For just as Jonah was three days and three nights in the belly of the great fish, so will the Son of Man be three days and three nights in the heart of the earth. (Matthew 12:38-40, ESV, see also Matthew 16:1-4, Mark 8:11-12, and Luke 11:29-30)

So, we see that Jesus himself became the sign of the New Covenant - OR - as Luke phrased it: "For as Jonah became a sign to the people of Nineveh, so will the Son of Man be to this generation." (Luke 11:30, ESV) Interestingly, the New Covenant also symbolically incorporated the signs associated with the other covenants into the corpus of the writings which bear its name (the New Testament). Paul wrote to the saints at Rome: "For circumcision indeed is of value if you obey the law, but if you break the law, your circumcision becomes uncircumcision. So, if a man who is uncircumcised keeps the precepts of the law, will not his uncircumcision be regarded as circumcision? Then he who is physically uncircumcised but keeps the law will condemn you who have the written code and circumcision but break the law. For no one is a Jew who is merely one outwardly, nor is circumcision outward and physical. But a Jew is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the letter. His praise is not from man but from God." (Romans 2:25-29, ESV)

Likewise, in the epistle to the Hebrews, we read this regarding the Sabbath: "So then, there remains a Sabbath rest for the people of God, for whoever has entered God's rest has also rested from his works as God did from his. Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience." (Hebrews 4:9-11, ESV) Indeed, just as the Sabbath was a sign for the Israelites to understand that it was God who made them holy, Christ is the one who made his disciples holy! Moreover, just as the rainbow continues to remind us that God once made a commitment to never again completely destroy life on this planet, Jesus was offered to ensure our eternal salvation in God's Kingdom! In short, ALL of the signs of the various covenants pointed to Jesus Christ - just as the star pointed to the place where the Messiah had made his first appearance on this earth!
