2 Corinthians 5:15

And that He died for all, &c. We judge also that He died for all, that they which live should not henceforth live for their own glory, or pleasure, or their desires, but for Christ, who by right of redemption has made us His servants; and as a servant does not labour and live for himself but for his lord, so should each of us be able to say: "I live, yet not I, but Christ liveth in me;" and, "My soul shall live to Him." Anselm says: " The soul of man should fail in itself to avail in Christ, who died that we should die to our sins, and who rose that we should rise to works of righteousness. What else is 'living not for themselves but for Him,' but living not according to the flesh in the hope of earthly vanities, but according to the Spirit, in hope of the resurrection which has already taken place in themselves in Christ?"
