The Gospel for the City in Genesis 21-22

In Genesis 21-22 Abraham’s faith that God would bless the nations through his offspring is now tested. Isaac, the son through whom the promise will be fulfilled, has become for Abraham the visible evidence of that promise. The underlying question of Genesis 22 is this:  Is Abraham’s faith still dependent on the Word of God or is it now placed in the physical presence of Isaac? Is Abraham walking by faith or is he walking by sight?

Abraham is ordered to offer the son of promise as a sacrifice. Abraham, in obedience to the God who called him and believing that God would resurrect the son of promise, takes his son to the mountain top and lays him on the altar of sacrifice.  God prevents Abraham from slaying Isaac and graciously supplies a substitute sacrifice.

The promise of numerous descendants and blessing to the nations is confirmed again to Abraham.

Abraham models the faith of all true followers of Christ. He believed that God could raise the dead.

Hebrews 11:17-19   17 ¶ By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was in the act of offering up his only son,  18 of whom it was said, “Through Isaac shall your offspring be named.”  19 He considered that God was able even to raise him from the dead, from which, figuratively speaking, he did receive him back.

Like Abraham, our present actions are based upon our faith in God’s future actions. Furthermore, we live on the other side of Christ’s resurrection and are called to an even deeper faith. The God who has raised Jesus from the dead is the God who assures us that through faith we participate in His resurrection. Immediately through faith we receive new life in the inaugurated kingdom of Jesus and ultimately are assured of resurrected life in the consummated kingdom of Jesus.

The promised offspring of Abraham who would bless the nations has come. We are recipients of that blessing as well as mediators of that blessing to the nations. That is why followers of Christ eschew ethnic pride; they deplore racism and mono-culturalism. Many believers today are reversing the white flight that abandoned cities for the safer suburbs. They realize that cities are where the nations of the world are congregating and that King Jesus, is a king for the nations.  In most major cities today, you can literally obey the command of Jesus to “go into all the world and make disciples of all nations.”

The Gospel for the City in Genesis 20

The promise of God to Abraham to create a new humanity through whom the nations would be blessed comes to fruition with the birth of Isaac.  In the midst of that joyous birth, the presence of Hagar and Ishmael appears to be a threat to Sarah who understands rightly that the promise of blessing to the nations comes through Isaac, not Ishmael. Under God’s direction, Abraham sends Hagar and her son away. God provides for them and promises that, as the seed of Abraham, the line of Ishmael would also become a great nation.

Abraham settles a dispute with Abimelech, king of the Philistines, over a well in the Negev.  Abimelech concedes to Abraham ownership of the well and Abraham makes a covenant with Abimelech affirming that the well, called Beersheba, belonged to Abraham.

Abraham worships El Elyon, the Most High God, at the well.  He now has a foothold in the land of promise, only a taste of the fuller promise yet to be fulfilled, for he is yet a sojourner in what is now the land of the Philistines.

Abraham , as we, lived between the times of inauguration and complete fulfillment. In the birth of Isaac and the digging of the well at Beersheba, the promise of a new humanity representing the kingdom of God is initiated, but not fulfilled. Even the initial taste of the promise is in the midst of struggle against adversaries like Ishmael and Abimelech.  Nevertheless, though God allows the struggle, He is faithful to His promises.  That initial taste of the promise encouraged Abraham to keep looking in faith for that ‘continuing city, whose builder and maker is God.’

Like Abraham, we live between inauguration and complete fulfillment. Even though our ‘taste’ of the world to come through life in the Spirit is real and satisfying in the inauguration of the kingdom of Jesus Christ, we yet long for the full and final expression of that kingdom in which the descendants of Abraham, both believing Jews and Gentiles, will enjoy the final ‘rest’ in the New Jerusalem.

Believers who live in urban centers perhaps are more aware of an ‘Abraham-like’ longing for that eternal city, as they experience the antithesis to that eternal city. Often the retreat to the suburbs is motivated by the pursuit of the ‘good life,’ a taste of heaven on earth. This retreat is often an escape from sin and its consequences rather than a calling of God to be ministers of mercy in a world that needs Jesus. Many believers in the suburbs already possess the ‘city’ they’ve longed for and have settled down quite comfortably with only a feint longing or memory of the continuing city whose builder and maker is God. Whether in the city or the suburbs, we must fight to not lose sight that we are sojourners here and that our hearts should be longing for the city whose builder and maker is God.

At times, to live in the city may be a choice to forgo ‘having it all now’ knowing that the best is yet to come; though there is enough allurement in urban life to capture anyone’s heart. Keeping your spiritual eyes wide open, city living may challenge you daily and make you more aware of the temporality of this life, i.e. that you are a sojourner in this world. Believers in the city should not be seeking utopia but a ministry among the nations from whom God is calling out a people for His name.
