Pictures in Noah's Ark

The truth of Scripture is eternal: it has always been true and will be true forever. But that truth was revealed to man progressively. The writer of Hebrews spoke of the Old Testament sacrificial system as "a shadow of good things to come, and not the very image of the things". Although we do not build doctrines upon these OT "shadows," yet in them we observe pictures of truth revealed later in Scripture. Thus, today we notice "Pictures in Noah's Ark."
