“Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset [us,] and let us run with patience the race that is set before us, Looking unto Jesus the author and finisher of [our] faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God. For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds. Ye have not yet resisted unto blood, striving against sin. And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him: For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth. If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons. Furthermore we have had fathers of our flesh which corrected [us,] and we gave [them] reverence: shall we not much rather be in subjection unto the Father of spirits, and live? For they verily for a few days chastened [us] after their own pleasure; but he for [our] profit, that [we] might be partakers of his holiness. Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby. Wherefore lift up the hands which hang down, and the feeble knees; And make straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed” (Hebrews 12:1-13).
Some quotes from Augustine (not a promotion of Augustine as a true Christian):
“Wherefore, though good and bad men suffer alike, we must not suppose that there is no difference between the men themselves, because there is no difference in what they both suffer. For even in the likeness of the sufferings, and under the same flail the straw is beaten small, while the grain is cleansed; and as the lees are not mixed with the oil, though squeezed out of the vat by the same pressure, so the same violence of affliction proves, purges, clarifies the good, but damns, ruins, exterminates the wicked. And thus it is that in the same affliction the wicked detest God and blaspheme, while the good pray and praise. So material a difference does it make, not what ills are suffered, but what kind of man suffers them. For, stirred up with the same movement, mud exhales a horrible stench, and ointment emits a fragrant odor”(Augustine).
“But call to remembrance the former days, in which, after ye were illuminated, ye endured a great fight of afflictions; Partly, whilst ye were made a gazingstock both by reproaches and afflictions; and partly, whilst ye became companions of them that were so used. For ye had compassion of me in my bonds, and took joyfully the spoiling of your goods, knowing in yourselves that ye have in heaven a better and an enduring substance. Cast not away therefore your confidence, which hath great recompence of reward. For ye have need of patience, that, after ye have done the will of God, ye might receive the promise. For yet a little while, and he that shall come will come, and will not tarry. Now the just shall live by faith: but if [any man] draw back, my soul shall have no pleasure in him. But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul” (Hebrews 10:32-39).
Another quote from the same:
“But as to those feebler spirits who, though they cannot be said to prefer earthly possessions to Christ, do yet cleave to them with a somewhat immoderate attachment, they have discovered by the pain of losing these things how much they were sinning in loving them” (Augustine).
And some Scripture:
“For whatever things were written before were written for our instruction, that through patience and encouragement of the Scriptures we might have hope” (Romans 15:4).
“And all these things happened to those [as] examples, and [it] was written for our warning, on whom the ends of the ages have come” (1 Corinthians 10:11).
“My brothers count [it] all joy when you fall into various trials, knowing that the proving of your faith works patience. But let patience have its perfective work, that you may be perfect and complete, lacking nothing” (James 1:2-4).
“Commit thy works unto the LORD, and thy thoughts shall be established” (Proverbs 16:3).
“For all this I considered in my heart even to declare all this, that the righteous, and the wise, and their works, [are] in the hand of God: no man knoweth either love or hatred [by] all [that is] before them. All [things come] alike to all: [there is] one event to the righteous, and to the wicked; to the good and to the clean, and to the unclean; to him that sacrificeth, and to him that sacrificeth not: as [is] the good, so [is] the sinner; [and] he that sweareth, as [he] that feareth an oath” (Ecclesiastes 9:1-2).
“It is not expedient for me doubtless to glory. I will come to visions and revelations of the Lord. I knew a man in Christ above fourteen years ago, (whether in the body, I cannot tell; or whether out of the body, I cannot tell: God knoweth;) such an one caught up to the third heaven. And I knew such a man, (whether in the body, or out of the body, I cannot tell: God knoweth;) such an one caught up to the third heaven. And I knew such a man, (whether in the body, or out of the body, I cannot tell: God knoweth;) How that he was caught up into paradise, and heard unspeakable words, which it is not lawful for a man to utter. Of such an one will I glory: yet of myself I will not glory, but in mine infirmities. For though I would desire to glory, I shall not be a fool; for I will say the truth: but [now] I forbear, lest any man should think of me above that which he seeth me [to be], or [that] he heareth of me. And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure. For this thing I besought the Lord thrice, that it might depart from me. And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ’s sake: for when I am weak, then am I strong” (2 Corinthians 12:1-10; underlining mine).
Paul was quite sensible of this preemptive thorn in his flesh. He petitioned God thrice for its removal. By God’s response Paul was also made sensible to the instruction, to the purpose, to the profit, and to the power (Greek: dunamis) of Christ overshadowing or resting upon him. 
 From Robertson’s Word Pictures
“May rest upon me (episkēnōsēi ep’ eme). Late and rare verb in first aorist active subjunctive with hina (final clause), to fix a tent upon, here upon Paul himself by a bold metaphor, as if the Shechinah of the Lord was overshadowing him (cf. Luk_9:34), the power (dunamis) of the Lord Jesus.”
