What more can we say about the death of Abraham than what the Word of the Lord in the Gospels contains, saying, “Concerning the resurrection of the dead, have you not read how he says in the bush: ‘the God of Abraham, and the God of Isaac and the God of Jacob’? Now he is not God of the dead but of the living. For all those are living.” Let us also therefore choose this kind of death, as also the apostle says, that “we may die to sin but live to God.” For indeed the death of Abraham should be understood to be such, which death has amplified his bosom so much that all the saints who come from the four parts of the earth “may be borne by the angels into the bosom of Abraham.”
