Noah’s Ark visually represents the Gospel message in the Ark as a “type” of Christ. The Bible tells us that the world had become so corrupt “And it repented the LORD that he had made man on the earth, and it grieved him at his heart … The earth also was corrupt before God, and the earth was filled with violence.” (Genesis 6:6, 11). Things have not changed in all the years since that time. “For all have sinned, and come short of the glory of God” (Romans 3:23).
In His holiness must judge and punish sin, “For the wages of sin is death” (Romans 6:23). Just as God is holy, He is also merciful. “But Noah found grace in the eyes of the LORD” (Genesis 6:8) and He provided a way of salvation.
Noah had 120 years to build the Ark. During that time the Bible tells us that Noah was “a preacher of righteousness” (2 Peter 2:5) pleading for all to repent of their sin and find refuge in the Ark for God is “not willing that any should perish, but that all should come to repentance” (2 Peter 3:9).
The image of Christ portrayed in the Ark offers many parallels.
The ark was constructed of wood. The cross upon which Jesus died was constructed of wood.
Noah was instructed to make a single door in the side of the Ark; it was the only entrance into the Ark, and access was controlled by God. Likewise, Jesus said that He is the door, and that no one comes to the Father except through Him.
Noah was instructed to cover the Ark with a covering of pitch within and without. The pitch sealed the Ark and made it watertight so that all inside would be saved. The blood of Jesus covers the sin of all who will put their faith and trust in Him, and His blood puts a seal of security on those that belong to him.
Finally, the Ark carried all of its passengers safely to the destination that God had prepared for them. Jesus said:
Let not your heart be troubled: ye believe in God, believe also in me. In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also. (John 14:1-3)
