Augustine of Hippo, On the Merits and Forgiveness of Sins, and on the Baptism of Infants I.48: From the Epistles to Timothy

And then to Timothy he says: “This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief. Howbeit for this cause I obtained mercy, that in me first Jesus Christ might show forth all long-suffering, for a pattern to them which should hereafter believe on Him to life everlasting.” He also says: “For there is one God and one Mediator between God and men, the man Christ Jesus; who gave Himself a ransom for all.” In his second Epistle to the same Timothy, he says: “Be not thou therefore ashamed of the testimony of our Lord, nor of me His prisoner: but be thou a fellow-labourer for the gospel, according to the power of God; who hath saved us, and called us with a holy calling, not according to our works, but according to His own purpose and grace, which was given us in Christ Jesus before the world began; but is now manifested by the coming of our Lord Jesus Christ, who hath abolished death, and hath brought life and immortality to light through the gospel.”
