Hi SadTimes,
I didn't want to leave you unanswered. Think of your DC, a daughter if you have one. How would you feel is she was in your position - hurting and confused (which is how your post reads). What would you say to her - would you shout and condemn?? Or would you hurt for her, feel sad, for her, want to comfort and hug and reassure her of your love for her??
I am sure it is the latter. God is our parent, and he's more a parent than any of us will ever be. When he looks at you he feels that you are hurting, regretting your actions regarding getting pregnant, wishing you'd never been in the position of needing an abortion.
Is he angry? - He is angry like when your 3 year old wanders off in the supermarket and when you find then you want to hug them and shout at them at the same time.
I had a time for a few years where I was really lost and did some things that were awful, that I wouldn't admit to my Christian friends. I'm in recovery from alcoholism. I've caused an awful lot of hurt. I went through that avoiding church thing because I didn't really know what to say to God. I tell you this because what I'm writing here is not from some ivory tower but my experience of God in the healing years that followed the awful years.
Don't let what you think God will think cloud how you relate to Him. There is no hierarchy of sin, with abortion and homosexuality up there as number one offenders, despite what various (usually American) campaigners would have us believe. There is just your heavenly Father, and his child, in his world, all damaged by sin. If you don't know what to ask for forgiveness for just yet, that's ok. Just keep the dialogue open, sit by His side, and give it time. Say sorry for what you honestly wish you hadn't done, and ask God to reveal what else He wants you to look at.
Have you told anyone in RL that shares your faith that you could have this sort of conversation with face to face? Does your church have any sort of listening/ counselling ministry? It would probably do you good to tell someone, when you are ready.
Thinking of you.
