Before Jesus came, the people were led by the law. In and of itself, the law was good for the purpose God intended for it to accomplish, which was to make them conscious of what was sinful and create a sense of guilt over it. However, although it showed the people what was wrong with them, it did nothing to help them change or improve. Now that the law has been replaced by grace and truth, Jesus and our belief in Him can change us. The Holy Spirit, also called the Spirit of grace, is the administrator of that transformation.
