Young Sister Lycia,
You do know that the devil comes in many Guises, He has tried to tempt you with a hedonistic lifestyle which you survived and came to join his flock . Now he is trying to shame you into believing that you are not worthy of his Love by reminding you of your past transgressions. I, for one, believe you should not replace this old picture of past life but keep it as a reminder that the Lord will give his love to a Harlot if she is willing to give herself to him.
Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Ephesians 2:9 Not of works, lest any man should boast.
and remember
Luke 5:20 And when he saw their faith, he said unto him, Man, thy sins are forgiven thee.
It is known that your faith is strong and prayers are with you.
YIC
