How do we know that the ark is a type of Christ?

In the biblical narrative, the ark represents Christ in that it saved Noah and his family from the divine judgment of the flood, symbolizing salvation through faith. Just like the ark kept its inhabitants safe, Christ offers protection to believers from God's wrath against sin. As stated in 2 Corinthians 5:17, when we are 'in Christ,' we become a new creation, symbolizing the liberation we receive as believers. The narrative of Noah leaving the ark parallels the liberation believers experience through Christ's redemptive work, confirming that the ark is indeed a type pointing to Christ's salvation.
