The question that has been asked so many times over the centuries is "Why do the wicked live and become old, Yes, become mighty in power?" (Job 21:7).
"Wherefore do the wicked live? They have become old, Yea, they have been mighty in wealth. Their seed is established, Before their face with them, And their offspring before their eyes. Their houses are peace without fear, Nor is a rod of God upon them. His bullock hath eaten corn, and doth not loath. His cow bringeth forth safely, And doth not miscarry. They send forth as a flock their sucklings, And their children skip, They lift themselves up at timbrel and harp, And rejoice at the sound of an organ. They wear out in good their days, And in a moment to Sheol go down. And they say to God, `Turn aside from us, And the knowledge of Thy ways We have not desired. What is the Mighty One that we serve Him? And what do we profit when we meet with Him?' Lo, not in their hand is their good, (The counsel of the wicked Hath been far from me.)" (Job 21:7-16)
"As nothing, have my steps slipped, For I have been envious of the boastful, The peace of the wicked I see, That there are no bands at their death, And their might is firm. In the misery of mortals they are not, And with common men they are not plagued. Therefore hath pride encircled them, Violence covereth them as a dress. Their eye hath come out from fat. The imaginations of the heart transgressed; They do corruptly, And they speak in the wickedness of oppression, From on high they speak. They have set in the heavens their mouth, And their tongue walketh in the earth. Therefore do His people return hither, And waters of fulness are wrung out to them. And they have said, `How hath God known? And is there knowledge in the Most High?' Lo, these are the wicked and easy ones of the age, They have increased strength. Only--a vain thing! I have purified my heart, And I wash in innocency my hands, And I am plagued all the day, And my reproof is every morning." (Psalms 73:2-14)
"Righteous art Thou, O Jehovah, When I plead towards thee, Only, judgments do I speak with Thee, Wherefore did the way of the wicked prosper? At rest have been all treacherous dealers. Thou hast planted them, yea, they have taken root, They go on, yea, they have made fruit, Near art Thou in their mouth, And far off from their reins. And Thou, O Jehovah, Thou hast known me, Thou seest me, and hast tried my heart with Thee, Draw them away as sheep to slaughter, And separate them for a day of slaughter. Till when doth the earth mourn, And the herb of the whole field wither? For the wickedness of those dwelling in it, Consumed have been beast and fowl, Because they said, `He doth not see our latter end." (Jeremiah 12:1-4)
"O LORD, how long shall I cry, and thou wilt not hear! even cry out unto thee of violence, and thou wilt not save! Why dost thou shew me iniquity, and cause me to behold grievance? for spoiling and violence are before me: and there are that raise up strife and contention. Therefore the law is slacked, and judgment doth never go forth: for the wicked doth compass about the righteous; therefore wrong judgment proceedeth." (Habakkuk 1:2-4)
“Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal; but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. For where your treasure is, there your heart will be also." (Matthew 6:19-21)
"Perverse disputings of men of corrupt minds, and destitute of the truth, supposing that gain is godliness: from such withdraw thyself. But godliness with contentment is great gain. For we brought nothing into this world, and it is certain we can carry nothing out. And having food and raiment let us be therewith content. But they that will be rich fall into temptation and a snare, and into many foolish and hurtful lusts, which drown men in destruction and perdition. For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows. But thou, O man of God, flee these things; and follow after righteousness, godliness, faith, love, patience, meekness." (1 Timothy 6: 5-11)
"Command those who are rich in this present age not to be haughty, nor to trust in uncertain riches but in the living God, who gives us richly all things to enjoy." (1 Timothy 6:17-18)
"Let the brother of low degree rejoice in that he is exalted: But the rich, in that he is made low: because as the flower of the grass he shall pass away. For the sun is no sooner risen with a burning heat, but it withereth the grass, and the flower thereof falleth, and the grace of the fashion of it perisheth: so also shall the rich man fade away in his ways." (James 1: 9-11)
"Come now, you rich, weep and howl for your miseries that are coming upon you! Your riches are corrupted, and your garments are moth-eaten. Your gold and silver are corroded, and their corrosion will be a witness against you and will eat your flesh like fire. You have heaped up treasure in the last days." (James 5:1-3)
"And Jesus looked round about, and saith unto his disciples, How hardly shall they that have riches enter into the kingdom of God! And the disciples were astonished at his words. But Jesus answereth again, and saith unto them, Children, how hard is it for them that trust in riches to enter into the kingdom of God! It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God." (Mark 10: 23-25)
Because people do not always suffer a penalty immediately for doing evil,
and they continue to have their days and wealth prolonged many think it is
unfair.
"Because sentence hath not been done on an evil work speedily, therefore the heart of the sons of man is full within them to do evil. Though a sinner is doing evil a hundred times, and prolonging himself for it, surely also I know that there is good to those fearing God, who fear before Him." (Ecclesiastes 8:11-12)
But if punishments and rewards were dealt out immediately they would do it only out of selfishness. God wants to know that we really want to please him and that we will remain true to him regardless of calamities, trials, hardships.
Also if you were blessed continually there is a good chance that you would take it for granted and forget where it came from.
"Beware that thou forget not the LORD thy God, in not keeping his commandments, and his judgments, and his statutes, which I command thee this day: Lest when thou hast eaten and art full, and hast built goodly houses, and dwelt therein; And when thy herds and thy flocks multiply, and thy silver and thy gold is multiplied, and all that thou hast is multiplied; Then thine heart be lifted up, and thou forget the LORD thy God, .. And thou say in thine heart, My power and the might of mine hand hath gotten me this wealth. " (Deuteronomy 8:11-17)
It comes down to, we must stick with it regardless of the physical circumstances we are going through.
