"I feel guilty over my adultery and divorce. I need encouragement!"

I struggle with guilt over my past adultery and divorce. When you warn people about not receiving God's grace, who are you talking to? Aren't believers forgiven and living under grace already? Help me understand, and I need encouragement. My son got taken in by a movement I'm worried about. I feel responsible and guilty! What can I do? What do you think of women participating in church? As deacons? As exhorters? What does the Bible say? And what about the two passages on women remaining silent? I'm so grateful for The Grace Message. Thank you!
