Furthermore...
Furthermore, according to this worldview which sketches out broad horizons for man, life is not restricted to this world, and even the life of this world is not restricted to material well- being or freedom from effort and pain. The believer in religion will see the world as a path that must be traversed, as a place of testing, as an arena of effort. In it, the righteousness of men's deeds is tested.
At the beginning of the next life, the good and the evil in the thoughts, beliefs, and actions of men will be measured in the most accurate of balances. God's justice will be revealed in its true aspect, and whatever deprivation man may have suffered in this world, whether material or otherwise, it will be made up to him. In the light of his destiny that awaits man, and given the essential nullity of the goods of the material world, man orients his conscious striving exclusively to God.
His aim becomes to live for Him and to die for Him. The vicissitudes of this world no longer claim his attention. He sees ephemeral things for what they are, and he allows nothing to seduce his heart. For he knows that the forces of seduction would cause his humanity to wither and draw him down into the whirlpool of materialistic misguidance. In conclusion, we would add that even apart from the question of receptivity, the existence of difference in the world does not imply injustice.
Oppression and injustice mean that someone is subjected to discrimination although he has a claim equal to that of someone else. But beings do not have any "claim" on God nor did they ever, so if some things enjoy superiority over others this cannot count as injustice. We have nothing of ourselves: each breath and each heartbeat, each thought and idea that passes through our mind, are taken from a stock that we do not own and have done nothing to build up.
That stock is a gift from God, bestowed on us at the moment of birth. Once we understand that whatever we have is nothing but a divine gift, it will become apparent that the differences among the gifts He gives men are based on His wisdom but have nothing to do with either justice or injustice, because there was no question of any merit or claim on our part. This finite and temporary life is a gift to us, a present from the Creator.
He has absolute discretion in deciding the type and quantity of the gift that He gives, and we have no claim upon Him.
