Tertullian

Since, therefore, shall then be accomplished the word which was written by the Creator, "O death, where is thy victory"-or thy struggle? "O death, where is thy sting? " -written, I say, by the Creator, for He wrote them by His prophet -to Him will belong the gift, that is, the kingdom, who proclaimed the word which is to be accomplished in the kingdom.

And to none other God does he tell us that "thanks" are due, for having enabled us to achieve "the victory" even over death, than to Him from whom he received the very expression of the exulting and triumphant challenge to the mortal foe.
