Pulpit magazine has lots of interesting articles. I especially like the series No Longer under the Law by Nathan Busenitz in which aims to enlighten us on The NT Christian's relationship to the OT law.
He says that this is not the same as New Covenant Theology, but it certainly seems very similar. I can't see any distinction, but am hoping to get some help on this soon.
Nathan is John MacArthur's personal assistant.
