Lord help this woman to forgive herself for whatever wrongs she did in the past. Also let her see that only you forgive us unconditionally, and you never bring up the past back to us. So she should confess her sins only to you and nobody else Lord. May she separate herself from all that know her past so there won't be anyone bringing it back to her, it's none of their business to have others know of it. These people are not friends but troublemaker and should be avoided. Stop those people short every time they will try to bring this child of yours past up. May her fiance see that if you have forgiven her, how much more he should forgive her? Specially when it happened before he met her and she has repented of it. Let him see that if he can't forgive her then you can't forgive him of his sins. Help him to understand the "The Lord's Prayer" where it says to "forgive our trespasses as we forgive those that trespass against us." So his un forgiveness to her is even worse since what she did was not to him, but before they even knew each other. Help them both to be able to put the past behind them and not look back anymore. Help him to understand this Lord and to trust her so they'll be able to have a happy life together. May they make you the cornerstone of their life, and if they marry of their marriage too so they can stand on solid ground and not in quicksand. May this be done for your Honor and Glory Heavenly Father to whom all power belongs. I pray and thank you in advance in Jesus Christ Precious Name, Amen!
