Without the gospel everything is useless and vain; without the gospel we are not Christians; without the gospel all riches is poverty, all wisdom folly before God; strength is weakness, and all the justice of man is under the condemnation of God. But by the knowledge of the gospel we are made children of God, brothers of Jesus Christ, fellow townsmen with the saints, citizens of the Kingdom of Heaven, heirs of God with Jesus Christ, by whom the poor are made rich, the weak strong, the fools wise, the sinner justified, the desolate comforted, the doubting sure, and slaves free. It is the power of God for the salvation of all those who believe.
It follows that every good thing we could think or desire is to be found in this same Jesus Christ alone. For, He was sold, to buy us back; captive, to deliver us; condemned, to absolve us; He was made a curse for our blessing, sin offering for our righteousness; marred that we may be made fair; He died for our life; so that by Him fury is made gentle, wrath appeased, darkness turned into light, fear reassured, despisal despised, debt canceled, labor lightened, sadness made merry, misfortune made fortunate, difficulty easy, disorder ordered, division united, ignominy ennobled, rebellion subjected, intimidation intimidated, ambush uncovered, assaults assailed, force forced back, combat combated, war warred against, vengeance avenged, torment tormented, damnation damned, the abyss sunk into the abyss, hell transfixed, death dead, mortality made immortal. In short, mercy has swallowed up all misery, and goodness all misfortune.
For all these things which were to be the weapons of the devil in his battle against us, and the sting of death to pierce us, are turned for us into exercises which we can turn to our profit. If we are able to boast with the apostle, saying, O hell, where is thy victory? O death, where is thy sting? it is because by the Spirit of Christ promised to the elect, we live no longer, but Christ lives in us; and we are by the same Spirit seated among those who are in heaven, so that for us the world is no more, even while our conversation [life] is in it; but we are content in all things, whether country, place, condition, clothing, meat, and all such things. And we are comforted in tribulation, joyful in sorrow, glorying under vituperation [verbal abuse], abounding in poverty, warmed in our nakedness, patient amongst evils, living in death.
This is what we should in short seek in the whole of Scripture: truly to know Jesus Christ, and the infinite riches that are comprised in Him and are offered to us by Him from God the Father.
