How did the resurrection declare Christ the Son of God 'with power'?

[theressomanywaystoloveya]

Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh; And declared [to be] the Son of God with power, according to the spirit of holiness, by the resurrection from the dead: - Rom. 1:3,4.

 

[BUSTER]

the grave could not hold Him who else do you know that has power over death?

 

[emelle]

because he has the power to come back from the death.

 

[Ross]

It looks over the Crucifixion and all pain as if it isn't there.
