How do we know Jesus is the Ark of salvation?

In the narrative of Noah's Ark, the ark itself serves as a type of Christ, illustrating how Jesus absorbs God's judgment and wrath on behalf of sinners. As the ark was designed by God to withstand the flood and save Noah and his family, Christ is uniquely designed by God as the means of salvation for His people. The pitch applied inside and outside the ark symbolizes the atonement and propitiation that Christ provides through His blood, covering the sins of those who trust in Him.

Moreover, the singular door of the ark signifies that there is only one way to salvation—through Christ alone. When Noah and his family entered the ark, they were saved from the flood, much like how believers, through faith in Jesus, are saved from eternal condemnation. This model underscores the certainty and sufficiency of Christ’s work, assuring us that those in Him are secure and safe from God’s judgment, affirming a core tenet of sovereign grace theology.
