Since you repented as your faith teaches you, your sin has been blotted away. God bless you for your courage.
The ultimate goal is to prevent abortions from happening, either by individual choice or by pri-life laws. You can only do that if you send the consistent message: abortion is wilful killing of babies.
It is not the condemnation of sin that hurts, but the sin itself.
I know--that is the primary and absolutely most important message. Sadly, I don't think it is always the most effective way of reaching a woman in crisis, of convincing her to make the right choice. Good Lord, it should be! But a woman waffling through the "should I or shouldn't I?" is in a very dangerous state. Its hard to immediately love something so unconditionally that you are willing to turn your life upside down. I know that sounds completely selfish, but there it is. In a way, that's what I try to appeal to in women (I volunteer at a crisis pregnancy center): I try to appeal to their selfishness. "You think giving up a few years of clubbing and whatnot is hard? Imagine living with a child you'll never be able to hold, until the day you die. Imagine knowing afresh, each day, that you have taken the life of your own flesh and blood." Eighteen years of, at worst, inconvenience or a lifetime without that daily regret and anguish and self-hatred and horror...how dearly I wish I could go back in time to myself as a cowardly teenager. I made the wrong decision for selfish reasons. I could have made the right decision for equally selfish reasons, but it would be the right decision.
