They, like all of us, will one day get to have a face to face talk with God about the life He has given us.  Ohhhh, then to have to speak to Him how we have affected others.... a sobering thought to consider..  For those who suffer regret, thank God for forgiveness and the Blood of the Lamb. And even tho' it is painful  and difficult, warn others of what you have gone through--no one else will present this truth. Godspeed.
