Forgiveness is a far cry from being healed though. Most people that I know of after they have been forgiven do not try to return to a state of innocence but remain in unsaved expectations and unhealed carnal desires and capabilities.
An example I will give is of pornography. A man can be saved, and married, and repress his sexual desires but after he is married it will all come out again. In times of stress or idleness he can return to pornography even though he has been saved and forgiven of it.
Another example is burn out. A woman has had numerous sexual partners both skilled and unskilled before she was saved. She courts a christian man and they do not have pre-marital sex. After marriage sex reminds her of being unsaved, and she's bored of it anyways since she's had so much of it. She denies her husband sexual needs and is quite content to occasionally remember her sexual adventures as she gets on to the real business of marriage- bills, working, and raising the children. Her spouse is the father to her children and the financial provider of the household but not her lover or husband any more. When she grows bored of playing house and bored of him and his fumbling attempts to seduce her (so unlike the skilled lovers in her past she thinks), she divorces him and takes the kids, the house, and his money for the next decade or two.
They are all 'good church going saved christians' but being saved does not equate having victory over strong holds and unsaved attitudes and experiences in their lives.
