When interpreting the OT and NT, each in light of the single, grammatical-historical meaning of a passage, two kinds of NT uses in the OT surface, one in which the NT writer observes the grammatical-historical sense of the OT passage and the other in which the NT writer goes beyond the grammatical-historical sense in his use of an OT passage. Inspired sensus plenior application (ISPA) designates the latter usage. Numerous passages illustrate each type of NT use of the OT. The ISPA type of usage does not grant contemporary interpreters the right to copy the methodology of the NT writers, nor does it violate the principle of single meaning. The ISPA meaning of the OT passage did not exist for man until the time of the NT citation, being occasioned by Israel’s rejection of her Messiah at His first advent. The ISPA approach approximates that advocated by Walton more closely than other explanations of the NT use of the OT. “Fulfillment” terminology in the NT is approximate only for events that literally fulfill events predicted in the OT.
