How do we know that Jesus is the fulfillment of Old Testament types like Noah's Ark?

We know that Jesus is the fulfillment of Old Testament types, including Noah's Ark, because the New Testament reveals these fulfillments, highlighting how Christ embodies these figures in His person and work. Hebrews 9 speaks of figures that were a shadow of the good things to come, and Noah's Ark prefigures Christ as the one who provides shelter from judgment. Just as the Ark preserved Noah and his family during the flood, Jesus preserves us from the eternal judgment of sin. Furthermore, 1 Peter 3:21 connects Noah's Ark to baptism in Christ, demonstrating how the waters that once obliterated the world now symbolize a new life found through faith in Him. Thus, the continuity between the Ark and Christ is evident in the themes of salvation, deliverance, and secure refuge.
