According to Luke, one of the things Jesus stressed to his disciples immediately after his resurrection was how to read the OT:
"Then beginning with Moses and with all the prophets, He explained to them the things concerning Himself in all the Scriptures." (Luke 24:27)
"Now He said to them, 'These are My words which I spoke to you while I was still with you, that all things which are written about Me in the Law of Moses and the Prophets and the Psalms must be fulfilled.' 45 Then He opened their minds to understand the Scriptures, 46 and He said to them, 'Thus it is written, that the Christ would suffer and rise again from the dead the third day, 47 and that repentance for forgiveness of sins would be proclaimed in His name to all the nations, beginning from Jerusalem. 48 You are witnesses of these things.'" (Luke 24:44-48)
In these two passages, Jesus makes it clear that if his disciples are to read the OT correctly, they must read it with a view to his suffering/resurrection and the proclamation of that message to the ends of the earth. In other words, if we read the OT without attempting to understand how that particular passage in some fashion points forward to Christ and the gospel, we are not reading the OT in the way that Jesus commands us to. I would call this a "gospel-centered hermeneutic." Only in the light of Jesus' death/resurrection and the proclamation of that event do we have the hermeneutical key for reading the OT in all its fullness.
