The grace and love of Christ can still change a persecutor of Christians, as with Saul who became Paul, to the vilest of sinners, as with the Son of Sam who became the son of hope.
“My name is David Berkowitz, and I am a prison inmate who has been incarcerated for more than forty years. I have been sentenced to prison for the rest of my life. My criminal case is well known and was called the Son of Sam shootings. It was twenty-nine years ago, when I was living in a cold and lonely prison cell, that God got a hold of my life. Here is my story of hope” (https://www.ariseandshine.org/testimony-translations.html).
