What does Genesis 6:22 mean?

In this passage, God has given Noah a colossal set of tasks. He is to build a container longer than a football field and taller than a four-story building. He is to make room inside for pairs of every kind of insect and animal. He is to prepare food for his family and these animals. And, the reason for this is so that those inside the ark can survive God's upcoming judgment on a wicked human race: a catastrophic flood of water.

Given all of that, this verse is remarkable in and of itself. Noah demonstrates his faith in and submission to God by simply obeying. He did everything God had commanded, and he did it "just as" God commanded it. We are given very few details in this passage. Surely, Noah was told more in person than we are in this passage. And yet, there is no doubt that Noah would have had many, many questions and concerns. But, despite these, he acts according to the commands of God. We were told in the beginning of this section (Genesis 6:9) that Noah was a righteous, blameless man who walked faithfully with God. This verse is evidence of that profound faithfulness.
