I give thanks to God that, taking compassion on me whom he had created and placed in this world, he delivered me by his power out of the deep darkness of idolatry, into which I was plunged, that he might bring me into the light of his gospel, and make me a partaker of the doctrine of salvation, of which I was most unworthy.
With the same goodness and mercy he has graciously and kindly borne with my multiplied transgressions and sins, for which I deserved to be rejected and cut off by him; and has also exercised towards me such great compassion and clemency, that he has condescended to use my labor in preaching and publishing the truth of his gospel. I also testify and declare that it is my full intention to pass the remainder of my life in the same faith and religion which he has delivered to me by his gospel, having no other defense or refuge of salvation than his gratuitous adoption, on which alone my safety depends.
I also embrace with my whole heart the mercy which he exercises towards me for the sake of Jesus Christ, atoning for my crimes by the merits of his death and passion, that in this way satisfaction may be made for all my transgressions and offenses, and the remembrance of them blotted out. I further testify and declare that, as a suppliant, I humbly implore of him to grant me to be so washed and purified by the blood of that sovereign Redeemer, shed for the sins of the human race, that I may be permitted to stand before his tribunal in the image of the Redeemer himself. [“The Will of John Calvin”]
