Who Needs the 10 Commandments?

As we introduce our study of the 10 Commandments, we asked how are we to view the 10 Commandments? Certainly, not as a means of salvation, but shows our need for salvation. Many view them as outdated, though they are not outdated, but an important guide for believers. Further still, many view the 10 Commandments as a killjoy, when actually they are a good gift from God.
