Quote: The OT Sheds Light on the NT

"Evangelical approaches to the Messiah in the OT often have focused on reading the NT back into the OT. I am suggesting that one should also move in the other direction. The OT sheds a great deal of light on the NT. Our primary objective should be to read the NT in light of the OT, not vice versa.

"The NT is not so much a guide to understanding the OT as it is the goal of understanding the OT. Unless we understand the OT picture of the Messiah, we will not recognize the NT picture of Jesus. The OT, not the NT, is the messianic searchlight cast upon the NT accounts of Jesus and the gospel."

-John Sailhamer, The Meaning of the Pentateuch, 246,233.
