The World Held its Breath
I don't think we can correctly assess the gravitas of what was at stake between Good Friday and Resurrection morning.
If Jesus Christ is not raised from the dead and I mean eternally raised from the dead, then He is just another dead dude.
If that would be so, then the sin of man would not have been atoned and just the sheer weight of the compilation of that and those yet to be committed would have ripped the world apart.
Secondly that line of humanity...Adam would have continued unabated and there would be no hope as the salt and light of the New Creation would not function as a savoring preservative element regarding the Salt, and there would be no illumination, no perspective of hope would be seen and the Adam line would have imploded by now and the world with it.
Third, there would be no justification, to initiate a New Creation, we would yet be in our sins. What secured the end of the Adamic line by the "Last Adam" was the institution of the Second Mankind with the resurrected Jesus Christ preeminently set forth as Head by God the Father.
"God has fulfilled this for us their children, in that He has raised up Jesus. As it is also written in the second Psalm:"
‘You are My Son, Today I have begotten You' Acts 13:33
This is not a declaration made to Jesus Christ in the manager in Nazareth, It is the declaration God Made concerning Jesus Christ at Joseph of Arimathea's tomb when He raised Him from the dead. "This Day I have begotten You"!!
The "Last Adam has become the "Second Mankind" He is the Firstborn from the dead that He might be the Firstborn among many brethren." Brethren that have been predestined to be conformed to His Image.
All creation was holding their breath..and then, on that Resurrection morning, the bated breath became shouts of acclimation...He's Alive, He's Alive, He's Alive"!!
