For your hands are defiled with blood
It is much, much worse than I have yet admitted. The prophet's words are for my ears, his accusing fingers are pointed at me, and I am condemned. Not only have I been less than steadfast in defending human life, but I have been one of those who shed the innocent blood. For all my pro-life talk, I myself am guilty of the crime of abortion.
and your fingers with iniquity
- Isaiah 59:3
O, but that was years ago, and, until the prophet pointed at me, I didn't know I was guilty; I really didn't. I knew abortion was wrong. That the deliberate killing of a wholly innocent little one was evil. I also knew that God forgives a repentant sinner, that great though the sin is, His mercy and forgiveness are greater. What I didn't know was that I was in need of repentance myself.
From the time that I saw those little ones as the the least of my brethren, I sought to come to their aid. Along with other pro-life folks, I prayed. I wrote letters and signed petitions. I prayed some more. I fasted. As the years passed, I lamented greatly that our prayers seem to go unheard. I cried out
Why have we fasted,This cry was heard, and God answered. But I did not like the answer.
and thou seest it not?
Why have we humbled ourselves,
and thou takest no knowledge of it? 
Yes, I prayed, and the prayer was heartfelt. I fasted, and the fast was in earnest. In the meantime, I worked my job, collected my pay, and willingly surrendered a goodly portion of that pay to the government. And I learned how that money was used to fund Planned Parenthood, Title X abortions, and contraception, abortion and population control programs around the world. And I slowly came to admit that I was feeding the dragon. The prophet's finger was pointed at me, and I stood condemned.
This was God's answer to my cry?? That my prayers are hollow and my fasting cheap as long as I keep willingly contributing to the crime?
But... but... but, I don't want to pay for the killing of those helpless babies! Er... uhmmm... I mean, this isn't my idea! But.. well... but... O, dear me!
Well, yes, it is my money, I suppose. I put forth the effort, the time, and the skills to obtain it. And some of it is used to slaughter the innocents. I can no longer deny the truth. OK... (sigh)... I admit it. I am guilty.
This, too, by the grace of God, is a matter for repentance.
