Great post! Did I highjack the thread? or is it okay?I'm going to work backward from your post. According to Paul in Romans, there would be no sin without the law. It is by the law that we know what sin is, because sin is failure to follow the law. Without language, there could be no law. The fall could never have happened.
But we were made in God's image, and in the beginning was the Word, and the Word was with God and the Word was God. God spoke and there was light. Language was inherent in the creation. It was His good will that we should be able to know and understand the law (which started out with just one commandment- don't eat that.)
Children and animals are innocent of the law because they are unable to comprehend it. The Christian faith is a construct of God.
