Mark 12:25 - Exposition

But are as angels in heaven —not "the angels;" the οἱ is omitted. The blessed, after the resurrection, will be like angels as to purity, as to a spiritual life, as to immortality, as to happiness and glory. There will be no necessity for marriages in heaven. Here, on earth, the father dies, but he lives on in his children after death. In heaven there is no death, but every one will live and be blessed for ever; and therefore it is that St. Luke adds here, "Neither can they die any more." St. Augustine says, "Marriages are on account of children; children on account of succession; succession on account of death. But in heaven, as there is no death, neither is there any marriage."
