“These are the two heads whereunto all the prophecies and predictions concerning Jesus Christ under the Old Testament are referred– namely, His sufferings, and the glory that ensued thereon (1 Peter 1:11).
All the prophets testified beforehand ‘of the sufferings of Christ, and the glory that should follow.’
So when He Himself opened the Scriptures unto His disciples, He gave them this as the sum of the doctrine contained in them, ‘Ought not Christ to have suffered these things, and to enter into His glory?’ (Luke 24:26). The same is frequently expressed elsewhere in Rom. 14:9 and Phil. 2:5–9.
So much as we know of Christ, His sufferings, and His glory, so much do we understand of the Scripture, and no more.”
