Many of you have taken a similar path.   If you've taken (illegal) drugs, then be the one that foremost speaks against drugs.   If you've had a violent past, speak against violence.  If you've committed adultery, then speak against the entrapments associated with it (you may need to use a different language, as in some circles adultery is neither clear what it is, or clearly not wrong ...though it "is" clearly wrong).  If you've had an abortion, then stand up and admit what you've went through ...and stand against abortion.   Don't let guilt tell you the lie that tells you that you can never be forgiven.   The Apostle Paul knew he was forgiven, and you should know it too.  The only thing that I can see that would get in the way of freeing you from the guilt is yourself.   But you must see the truth.   If you continue to argue for the rights of abortion, how can you free yourself from the guilt?   The Apostle Paul did not deny what he had done ...and he repented.   He changed!!
