Is there ever a time that the OT Law can be referred to as a guideline without being accused of falling out from under grace? Some things are very specific in the NT, as for guidelines for right living as a christian, but others are not. The things that are not, but are in the OT, can show us answers to some questions. But if we use them as reference to a guideline, many will say that it is OT and we are no longer under the Law. If we cannot use OT Law as a guide, then why do we have the OT? For history purposes? Any other reasons?
