Indeed, the believer should accept whatever comes with a gentle and thankful heart, because he knows that it is ordained by the Lord. Moreover, he must not stubbornly resist the rule of God into whose power he has placed himself and all his affairs.
So let the Christian make it his priority to drive from his breast that foolish and unfortunate comfort of pagans, who, in order to bolster their spirits against all adverse events, credit those events to fortune. They think it’s silly to be angry at fortune, since she is reckless, aimless, and blind – inflicting her wounds equally on the deserving and undeserving. In contrast, the rule of godliness is to recognize that God’s hand is the sole judge and governor of every fortune, and because His hand is not recklessly driven to fury, it distributes to us both good and ill according to His orderly righteousness.
John Calvin, A Little Book on the Christian Life (pgs. 53-54)
But on day, as I was passing in the field, and that too with some dashes on my conscience, fearing lest yet all was not right, suddenly this sentence fell upon my soul, ‘Thy righteousness is in heaven’; and methought withal, I saw, with the eyes of my soul, Jesus Christ at God’s right hand; there, I say, is my righteousness; so that wherever I was, or whatever I was a-doing, God could not say of me, ‘He wants my righteousness,’ for that was just before Him. I also saw, moreover, that it was not my good frame of heart that made my righteousness better, nor yet my bad frame that made my righteousness worse; for my righteousness was Jesus Christ Himself, the same yesterday, today, and forever (Heb. 13:8). Now did my chains fall off my legs indeed, I was loosed from my afflictions and irons, my temptations had fled away; so that, from that time, those dreadful Scriptures of God left off to trouble me now; now went I also home rejoicing, for the grace and love of God.
John Bunyan, quoted in The Unquenchable Flame by Michael Reeves (pg. 175).
