Kurios (κύριος) in the OT and NT

If the authors of the NT believed that the God referred to in the OT was at times the pre-existent Christ or a prophecy of Christ, how could they convey this idea to their readers? What must be in order for what is to be what it is?

When κύριος (kurios) in the NT is the equivalent of יְהֹוָה (YHWH) in the OT, the divine usage cannot be denied or weakened.
