25 But as for you, my beloved, have no doubt as to the Resurrection of the dead. For the living mouth (of God) testifies:— I cause to die and I make alive. And both of them proceeded out of one mouth. And as we are sure that He causes to die, and we see it; so also it is sure and worthy of belief, that He makes alive. And from all that I have explained to you, receive and believe that in the day of the Resurrection your body shall arise in its entirety, and you shall receive from our Lord the reward of your faith, and in all that you have believed, you shall rejoice and be made glad.
