That what we suffer in this world is of less account than is the reward which is promised
In the Epistle of Paul to the Romans: “The sufferings of this present time are not worthy of comparison with the glory that is to come after, which shall be revealed in us.” Of this same thing in the Maccabees: “O Lord, who hast the holy knowledge, it is manifest that while I might be delivered from death, I am suffering most cruel pains of body, being beaten with whips; yet in spirit I suffer these things willingly, because of the fear of your own self.” Also in the same place: “You indeed, being powerless, destroyest us out of this present life; but the King of the world shall raise us up who have died for His laws into the eternal resurrection of life.” Also in the same place: “It is better that, given up to death by men, we should expect hope from God to be raised again by Him.
For there shall be no resurrection to life for you.” Also in the same place: “Having power among men, although you are corruptible, you do what you will. But think not that our race is forsaken of God. Sustain, and see how His great power will torment, you and your seed.” Also in the same place: Do not err without cause; for we suffer these things on our own accounts, as sinners against our God. But think not that you shall be unpunished, having undertaken to fight against God.
