93 We are all born, and we shall all rise again, but in each state, whether of living or of living again, grace differs and the condition differs. For, “in a moment, in the twinkling of an eye, at the last trump, the dead shall rise incorruptible and we shall be changed.” Moreover, in death itself some rest, and some live. Rest is good, but life is better. And so the Apostle rouses him that is resting to life, saying: “Rise, you that sleepest, and arise from the dead, and Christ shall give you light.” Therefore he is aroused that he may live, that he may be like to Paul, that he may be able to say: “For we that are alive shall not prevent those that are asleep.” He speaks not here of the common manner of life, and the breath which we all alike enjoy, but of the merit of the resurrection. For, having said, “And the dead which are in Christ shall rise first,” he adds further; “And we that are alive shall together with them be caught up in the clouds, to meet Christ in the air.”
