Chapter 1
The Gospel Starts with a Promise:
Relationship in the Spirit
Just for a moment, forget about sin. Forget about the debt we owe and the prospect of Godâs punishment. Those are all important things to consider, and we will consider them soon enough. But for the moment, I want to focus on something else: instead of sin, I want to think about the deep needs that define our humanity. To be human is to be aware that we yearn for things that we just canât get on our own, whatever our culture of self-sufficiency might tell us. We desire to be connected to something outside ourselves. We long to know why we exist at all. These needs and longings are central to the Bibleâs story. The gospel starts with a promise that addresses the deepest of human needs. Where relationships are broken, the gospel brings restoration.
The Covenants: Godâs Plan to Restore Relationships
The Abrahamic Covenant
The gospel didnât begin in Matthew 1:1. It began many centuries earlier in the dusty regions of the Middle East. God made a promise to Abraham, an old man who would give rise to a special people. In the midst of a world that had ignored its Creator for the elevation of their own glory (Gen 11), God moved to deliver humanity from its own foibles. In Genesis 12:1â3, God made a commitment with Abraham:
The LORD said to Abram:
Go out from your land,
your relatives,
and your fatherâs house
to the land that I will show you.
I will make you into a great nation,
I will bless you,
I will make your name great,
and you will be a blessing.
I will bless those who bless you,
I will curse those who treat you with contempt,
and all the peoples on earth
will be blessed through you.
That commitment became known as the Abrahamic covenant. Perhaps the greatest of Godâs promises to Abraham was this: through Abraham, Godâs blessing would penetrate throughout the world. In that first declaration of the promise, God offered no details as to how this blessing would spread. That story would develop across several centuries and inspired writers. In that unfolding story is our storyâour need for promise and the hope of restoration.
The context of this initial promise is important. In Genesis 1â11 we see how humanity had gone its own way, consistently going astray from the Creator. Whether we think of the individual acts of Adam or Cain or turn to the corporate actions before the flood or in building the tower of Babel, people showed a consistent tendency, one they still have, to turn away God and toward their own interests. In many ways, the story of the Bible is the story of Godâs stubborn faithfulness to His creation and those He had made in His own imageâHis commitment to pursue them in steadfast love and patience. Godâs love is the core of the gospel. The needs of humanity have run deep for a long time.
Godâs promise to Abraham grew. Part of the original promise was that Abraham would father a special seed (Gen 12:2), a people in touch with the true God. That storyâthe story of Israelâs originsâis told from Genesis through Deuteronomy (Gen 13:13â17).1 Abraham did father a seed in the figures of Isaac, Jacob, and the twelve sons who followed Jacob, known as the patriarchs. From them emerged the nation known as Israel. Godâs program was revealed to this people. They were the bearers of Godâs promise and revelation. They experienced a deliverance through Moses, pictured in a God who kept an ear open to people. They became a nation called to honor God (Exod 19:3â6).2
The Davidic Covenant
Israel, however, had her own hopes, and they didnât always line up with Godâs hopes for her. She longed for a king like the other nations had; God was not good enough for them. God noted that the Israelitesâ request for a king was really a rejection of Him (1 Sam 8:6â7); nevertheless, He graciously granted their desire and through this eventually extended the promise He had made to Abraham.3 This extended promise, known as the Davidic covenant, was a line of kings from the house of David (2 Sam 7:8â16):
âNow this is what you are to say to My servant David:
âThis is what the LORD of Hosts says: I took you from the pasture and from following the sheep to be ruler over My people Israel. I have been with you wherever you have gone, and I have destroyed all your enemies before you. I will make a name for you like that of the greatest in the land. I will establish a place for My people Israel and plant them, so that they may live there and not be disturbed again. . . .
âWhen your time comes and you rest with your fathers, I will raise up after you your descendant, who will come from your body, and I will establish his kingdom. He will build a house for My name, and I will establish the throne of his kingdom forever. I will be a father to him, and he will be a son to Me. When he does wrong, I will discipline him with a human rod and with blows from others. But My faithful love will never leave him as I removed it from Saul; I removed him from your way. Your house and kingdom will endure before Me forever, and your throne will be established forever.ââ
This regal line had a special relationship to God as His representative. The king of this dynasty was a son to God and God was his father (v. 14). Out of this promise came the hope for a unique king who would be the kind of ruler God desired. Out of this promise came the hope of a Messiah, a king who would bring peace and establish righteousness in line with promises God made originally to Abraham.
The New Covenant
The majority of Israelâs kings failed. They did not live up to Godâs ideals, reflecting instead the pattern of rebellion we have seen already. More often than not, they went their own way. Eventually God judged the nation, scattering them through war and exile. It was in this context that God promised a new covenant: a commitment to write His righteousness on the hearts of people and to fix them from the inside out with His very own presence and power. That commitment was revealed through Jeremiah (Jer 31:31â34):
âLook, the days are comingââthis is the LORDâs declarationââwhen I will make a new covenant with the house of Israel and with the house of Judah. This one will not be like the covenant I made with their ancestors when I took them by the hand to bring them out of the land of Egyptâa covenant they broke even though I had married themââthe LORDâs declaration. âInstead, this is the covenant I will make with the house of Israel after those daysââthe LORDâs declaration. âI will place My law within them and write it on their hearts. I will be their God, and they will be My people. No longer will one teach his neighbor or his brother, saying: Know the LORD, for they will all know Me, from the least to the greatest of themââthe LORDâs declaration. âFor I will forgive their wrongdoing and never again remember their sin.â
Two key ingredients came with this elaboration of Godâs promise. First, there would be forgiveness of sin; second, Godâs law would be written on the heart. That long history of unfaithfulnessâeven by Godâs own peopleâdemonstrated that human beings didnât have it within themselves to keep their end of the covenant bargain. They needed Godâs presence and power within them.
Forgiveness never stood alone; it was designed to provide the way to a restored relationship with God. Consider what God said through Ezekiel:
I will also sprinkle clean water on you, and you will be clean. I will cleanse you from all your impurities and all your idols. I will give you a new heart and put a new spirit within you; I will remove your heart of stone and give you a heart of flesh. I will place My Spirit within you and cause you to follow My statutes and carefully observe My ordinances. (Ezek 36:25â27)
A new heart. A new Spirit. A new start. If Godâs people are going to obey Godâs law consistently, it wonât be by trying harder. It will be by Godâs Spirit dwelling within them.
Summary
This overview of the promise of the Old Testament shows that behind the gospel stands the promise of three covenants that actually form a singular promise of God to fashion a people who themselves are a reflection of Godâs promise and blessing living in a world filled with need. Together the Abrahamic, Davidic, and New covenants form the gospelâs backbone. God would form a people through whom the world would be blessed. He would do it through a promised king, a Messiah. That king would bring two key things the world desperately needed: forgiveness and a restored relationship with the living God. The two were always connected to be good news from God.
The Proclamation: From John the Baptist to Jesus
Luke 3:16
Tucked away in Lukeâs Gospel is a passage most of us pass by very quickly, yet in it are some of the most profound things said in the entire Bible. Itâs too bad Luke 3:16 is not as well known in the church as John 3:16. The promise and revelation in Luke 3:16 literally run through all of Luke and Acts.4 In this verse, John the Baptist says, âI baptize you with water, but One is coming who is more powerful than I. I am not worthy to untie the strap of His sandals. He will baptize you with the Holy Spirit and fire.â
John made this remark in response to speculation that he might be the Christ. What is the sign of the new era? Godâs giving of His Spirit to His peopleânot the outward, physical sign of water baptism, but the inward sign of a Spirit baptism. This new era will come in the person of the One who follows John: Jesus Himself. In bringing the Spirit, Jesus will bring a renewed relationship. Remember what Ezekiel said? âI will give you a new heart and put a new spirit within you.â According to John the Baptist, Jesus was coming to fulfill that promise.
But there is more to this verse. It is found in the remark that John was not worthy to unstrap the sandal of the One to Come. Two points help us to appreciate what John is affirming. First, John says this as a prophet of God. In the vocational ladder of jobs God can give, few rank higher than prophet. In fact, later Jesus called John the greatest born of woman (Luke 7:28).5 So this is not just anyone saying he is unworthy to serve the One to Comeâit is a prophet of God, the greatest of the prophets at that.
Second, let us consider Johnâs saying that he is not worthy to untie the strap of his masterâs sandal. In Judaism, a person was not to become a slave. However, if he did, there was one thing later Jewish tradition noted a Hebrew slave should never do: he should never untie the strap of his masterâs sandal in order to wash his feet (Mekilta de Rabbi Ishmael Nezikin 1 on Exod 21:2).6 Unstrapping a masterâs sandal was seen as too demeaning for a Hebrew to perform.
The difference between John as a prophet and the person of the One to Come is so great that John, even though he is a prophet, is not worthy to perform even the most demeaning task of a slave. The One to Come is that unique. The significance of this point cannot be overstated. The Messiah to come is a figure of a different order. The chasm between Him and a prophet is vast. The One who brings Godâs promise is not merely another in a line of prophets but someone in a completely different, utterly unique category.
I love to make this point for those who tend to see Jesus as just another religious great. That is not how the person who pointed to Him saw it at all. The difference between them was too great for them to be seen in the same light.
I used this passage once in India to explain to a Hindi audience just how unique the Promised One is. My point was that John the Baptist was a figure whose activity was predicted in the Bible centuries before he ministered (Isa 40:3â5).7 Not too many of us have our career outlined for us in advance! Yet despite Johnâs high position in Godâs plan and program, the role of the One to Come was even more elevated. Even as a prophet, John would have been honored to have done a most demeaning task for Him and felt unworthy to perform such a task.
The bottom line of the new eraâs arrival is the coming of the Spirit. That is the provision that shows the promise of God has come. The goal of all of this covenant activity is to restore a lost rela...
