The ten commandments are still God's law. His law shows us how imperfect and horrible we all really are and helps bring us to God on our knees to ask for mercy and grace. And He is gracious, and He is loving. I am so thankful to God that his mother gave birth to him and gave him up for adoption. He was adopted by a family who wouldn't have been able to have children otherwise, and he was loved fully and is the most wonderful man in the world and the father of my two children.
Sin is sin.

In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move. I think you will like this story.
