My friend the hammer poses the question: "Which is more significant, the effects that have come through the rebellion of Adam, or the effects that have come through the resurrection of Jesus Christ?"
God helping, I hope to identify, throughout the Scriptures, evidences that in every area of life we are far better off under the effects of the resurrection than we are under the effects of the curse that came through Adam.
To begin the journey, let us look at the issue of nations.
These were the families of the sons of Noah, according to their generations, in their nations; and from these the nations were divided on the earth after the flood. (Genesis 10:32)
Therefore its name is called Babel, because there the LORD confused the language of all the earth; and from there the LORD scattered them abroad over the face of all the earth. (Genesis 11:9)
As a result of the curse upon Adam's rebellion, for many centuries, nations have been separated by language barriers, religious practices, cultural distinctives, historical precedents and fear.
On the other hand, after the resurrection of Jesus, God has made a way for these barriers to be pulled down. This began on the day of Pentecost.
1 When the Day of Pentecost had fully come, they were all with one accord in one place. 2 And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. 3 Then there appeared to them divided tongues, as of fire, and one sat upon each of them. 4 And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance.
The Crowd’s Response 5 And there were dwelling in Jerusalem Jews, devout men, from every nation under heaven. 6 And when this sound occurred, the multitude came together, and were confused, because everyone heard them speak in his own language. 7 Then they were all amazed and marveled, saying to one another, “Look, are not all these who speak Galileans? 8 And how is it that we hear, each in our own language in which we were born? 9 Parthians and Medes and Elamites, those dwelling in Mesopotamia, Judea and Cappadocia, Pontus and Asia, 10 Phrygia and Pamphylia, Egypt and the parts of Libya adjoining Cyrene, visitors from Rome, both Jews and proselytes, 11 Cretans and Arabs—we hear them speaking in our own tongues the wonderful works of God.” 12 So they were all amazed and perplexed, saying to one another, “Whatever could this mean?” 13 Others mocking said, “They are full of new wine.”
Peter’s Sermon 14 But Peter, standing up with the eleven, raised his voice and said to them, “Men of Judea and all who dwell in Jerusalem, let this be known to you, and heed my words. 15 For these are not drunk, as you suppose, since it is only the third hour of the day. 16 But this is what was spoken by the prophet Joel: 17 ‘ And it shall come to pass in the last days, says God, That I will pour out of My Spirit on all flesh; Your sons and your daughters shall prophesy, Your young men shall see visions, Your old men shall dream dreams. 18 And on My menservants and on My maidservants I will pour out My Spirit in those days; And they shall prophesy. 19 I will show wonders in heaven above And signs in the earth beneath: Blood and fire and vapor of smoke. 20 The sun shall be turned into darkness, And the moon into blood, Before the coming of the great and awesome day of the LORD. 21 And it shall come to pass That whoever calls on the name of the LORD Shall be saved.’22 “Men of Israel, hear these words: Jesus of Nazareth, a Man attested by God to you by miracles, wonders, and signs which God did through Him in your midst, as you yourselves also know— 23 Him, being delivered by the determined purpose and foreknowledge of God, you have taken by lawless hands, have crucified, and put to death; 24 whom God raised up, having loosed the pains of death, because it was not possible that He should be held by it. 25 For David says concerning Him: ‘ I foresaw the LORD always before my face, For He is at my right hand, that I may not be shaken. 26 Therefore my heart rejoiced, and my tongue was glad; Moreover my flesh also will rest in hope. 27 For You will not leave my soul in Hades, Nor will You allow Your Holy One to see corruption. 28 You have made known to me the ways of life; You will make me full of joy in Your presence.’29 “Men and brethren, let me speak freely to you of the patriarch David, that he is both dead and buried, and his tomb is with us to this day. 30 Therefore, being a prophet, and knowing that God had sworn with an oath to him that of the fruit of his body, according to the flesh, He would raise up the Christ to sit on his throne, 31 he, foreseeing this, spoke concerning the resurrection of the Christ, that His soul was not left in Hades, nor did His flesh see corruption. 32 This Jesus God has raised up, of which we are all witnesses. 33 Therefore being exalted to the right hand of God, and having received from the Father the promise of the Holy Spirit, He poured out this which you now see and hear. (Acts 2: 1-29)
In my own personal experience, having lived in a Warlpiri community for five years, the curltural barriers were, on the surface, insurmountable. However, through the glorious power of Jesus' resurrection, I came to know many of the Warlpiri people in Christ Jesus. In all honesty, those people are some of my most treasured friends and adopted family - and I know that the feeling is mutual.
The curse that came through Adam divides nations, but the glorious resurrection of Jesus Christ enables the members of all nations to become a part of one new nation, the New Israel of God, in Christ Jesus - one family with one Father.
