Until recently, 8-year-old Arkinya Graham had never met her father. While they have grown close talking over the phone for the past six months, her father Johnny Trey" Williams is serving 23 years in a Michigan prison for second-degree murder. ABC News' "Nightline" was given access to go behind prison walls ... as Arkinya met her dad for the first time. Their special visit is part of a prison ministry program called "One Day with God" that is designed to help children reconcile with their parents behind bars. The two-day program is part family reunion, part intervention. On the first day, the dads get a seminar on the importance of fatherhood. On the second day, they get to ... spend a rare day doing various activities with their kids. "Children are the silent victims," said One Day with God founder Scottie Barnes. "[There is an] importance of these boys and girls having relationships with their mothers and fathers who are incarcerated across America." Barnes says her own father ... spent most of her childhood behind bars. "I never had a hug. I never even been told 'I love you' by my dad," Barnes said. "The little children ... want to be loved. They want to be somebody proud of them." Children of incarcerated parents are six times more likely to end up incarcerated themselves. One Day with God is working to end the cycle of reincarceration. At a time when family programs are being cut in prison systems, this program is operating in seven states, [and] expanding to five other prisons in Michigan alone.
