This book is made up of two parts. Part one: "LIFE IS NOT FAIR"
Life is not fair towards mortality. Our mortality lives as if it will never die and die as if we never lived. We are constantly in dread of the uncertain and the events of life though they move in cycles as history always repeats itself are unpredictable. The worst can happen to the good and the best can happen to bad people. Good things happen to bad people notwithstanding their atrocities and bad things happen to the good and the innocent nonetheless their devotion, piety, uprightness. It is just a matter of the unpredictability of circumstances.
No one can understand the vicissitudes of fortune. How life selects and fate reduces men. Many are called but few are chosen. Who then is chosen? Those trusting in His grace and not of their own accord. For many, it is of their strength, wits that they live and not through the mercies of God. By their strength in religion, the self righteous boast of their success and divine favour and preservation and the destruction of another. But favour, preservation and destruction is a matter of "the times"-whims of fate. If the righteous would scarcely be saved, then the time of the reign of divine terror would be shortened for the elect to live through-survive the perils of the times. Thus, preservation and destruction, favour and misfortune is a matter of the times we live in and scaling through is not by our very efforts but through divine selection. Others are selected to show how the righteous suffer affliction of the wicked and others how the wicked suffer ill fate and others the preservation of the righteous and others the salvation for the evil one. It is divine selection and the order-ordination of the times (vicissitudes of fate) that makes destruction, preservation, favour or misfortune. Thus the scripture:
"This is a divine revelation. The Lord spoke his word to Israel through Malachi.
"I loved you," says the Lord.
"But you ask, 'How did you love us?'
"Wasn't Esau Jacob's brother?" declares the Lord. "I loved Jacob, but Esau I hated. I turned his mountains into a wasteland and left his inheritance to the jackals in the desert.
"The descendants of Esau may say, 'We have been beaten down, but we will rebuild the ruins.'
"Yet, this is what the Lord of Armies says: They may rebuild, but I will tear it down. They will be called 'the Wicked Land' and 'the people with whom the Lord is always angry.' You will see these things with your own eyes and say, 'Even outside the borders of Israel the Lord is great.'"
-Malachi 1:1-5. GW

Part two: BUT GOD GIVES THE GRACE
[Romans 11:6.NKJV]: "And if by grace, then it is no longer of works; otherwise grace is no longer grace. But if it is of works, it is no longer grace; otherwise work is no longer work." "But by the grace of God I am what I am, and His grace toward me was not in vain; but I labored more abundantly than they all, yet not I, but the grace of God which was with me."
-1 Corinthians 15:10.NKJV
The grace to work is the hope of our common mortality nonetheless the bludgeoning of fate. Thus, [Philippians 2:12. KJ21]: "work out your own salvation with fear and trembling."
When we face difficult circumstances, it can be easy to feel alone and abandoned. But God's grace reminds us that we are not alone, and that we have a helper who is always with us. It is a source of strength and comfort that can give us the courage to face whatever challenges come our way.
The grace of God also reminds us that there is more to life than just what we can see. Even though life may seem unfair, God has a bigger plan for us. He is working behind the scenes to bring about good things in our lives, even when we can't see them.
