7:15 the Jews marvelled. Jesus’ wisdom was, indeed, a marvel. He had never studied in a rabbinical school, but He had studied the Scriptures on His own from childhood, so that He had “increased in wisdom and stature, and in favour with God and man” (Luke 2:52). His profound knowledge of Scripture, acquired through application of His own perfect humanity, uncontaminated by either inherent sin or actual sin, is indicated by His frequent quoting and incisive interpretation of Scripture. Just when or how or by what process His human nature became aware of His eternally preexistent divine nature must remain unfathomably mysterious to our own limited understanding. By this time in His life, however, both natures were fully manifest to Himself, so that we can see both co-existing in His life and teachings.
