Fulgentius of Ruspe

“When the wicked turn away from the wickedness they have committed and do what is lawful and right, they shall save their life. Because they considered and turned away from all the transgressions that they had committed, they shall surely live. They shall not die.” Each statement is true because each is divine, whether it is that the just person when he will have turned away from his righteousness, all his righteous deeds will be consigned to oblivion, or whether it is that the wicked person, when he will have been converted from wickedness to righteousness, will be saved, and all his wicked deeds will not be remembered.

At whatever age a person will do true penance for his sins and change his life for the better under the illumination of God, he will not be deprived of the gift of forgiveness.

God gives a new heart so that we may walk in his justifications, which are about beginning a good will. He also gives it so that we may observe and do his judgments, which are about doing good works.
