It is the contention of God’s adversary, Satan, that those who do the divine will are basically selfish. Respecting faithful Job, the adversary declared: “Everything that a man has he will give in behalf of his soul.

Job 2:4,

By faithful endurance under suffering, we share in proving Satan’s contention to be a lie and share in vindicating the good name of our heavenly Father, who trusts his loyal servants. What if Jehovah were to allow Satan, by means of his agents, to subject true Christians to very cruel treatment that ended in death or crippling infirmity? What if some were even sexually assaulted or abused in other vile ways? These things are shocking. Yet there is nothing beyond the power of our heavenly Father to rectify fully in his due time. So, in some cases, he may see fit to let the trial be pushed to such an extreme point. Through faithfulness, even to the point of death, God’s servants are thus given the opportunity to show beyond denial the genuineness of their devotion.
