Athanasius Of Alexandria said this quote

Even on the cross He did not hide Himself from sight; rather, He made all creation witness to the presence of its Maker.

~ Athanasius Of Alexandria

The body of the Word, then, being a real human body, in spite of its having been uniquely formed from a virgin, was of itself mortal and, like other bodies, liable to death. But the indwelling of the Word loosed it from this natural liability, so that corruption could not touch it. Thus is happened that two opposite marvels took place at once: the death of all was consummated in the Lord's body; yet, because the Word was in it, death and corruption were in the same act utterly abolished.

~ Athanasius Of Alexandria

He, the Life of all, our Lord and Saviour, did not arrange the manner of his own death lest He should seem to be afraid of some other kind. No. He accepted and bore upon the cross a death inflicted by others, and those other His special enemies, a death which to them was supremely terrible and by no means to be faced; and He did this in order that, by destroying even this death, He might Himself be believed to be the Life, and the power of death be recognised as finally annulled. A marvellous and mighty paradox has thus occurred, for the death which they thought to inflict on Him as dishonour and disgrace has become the glorious monument to death's defeat.

~ Athanasius Of Alexandria

Dead men cannot take effective action; their power of influence on others lasts only till the grave. Deeds and actions that energise others belong only to the living. Well, then, look at the facts in this case. The Saviour is working mightily among men, every day He is invisibly persuading numbers of people all over the world, both within and beyond the Greek-speaking world, to accept His faith and be obedient to His teaching. Can anyone, in face of this, still doubt that He has risen and lives, or rather that He is Himself the Life? Does a dead man prick the consciences of men...?
