The water decreased steadily until the tenth month; in the tenth month, on the first day of the month, the tops of the mountains became visible. (Genesis 8:5)The first sight of land... oh what a sight it must have been! At first, the thought of mountains becoming visible may not seem all that exciting. But just think how exciting it must have been for Noah's household... since the 40th day of the flood, all the mountains had been hidden deep in the water. For over 6 months (183 days), Noah's household did not see any land!
But then, in the tenth month, on the first day of the month, Noah's household finally spotted land! Not only did they spot land, but Noah's household became the first humans to see the post-flood world. In a sense, the world that they saw had been cleansed, purified. But it was only a temporary cleansing. However glorious of a sight the mountains were, sin had not been abolished in the flood. The creation was still groaning (Romans 8:22). Noah's household was still living in a fallen planet.
As Noah's household gazed at the emerging mountains, one by one poking up out of the depths of the sea... As they gazed at the mountains, which their future descendants would also gaze at throughout history... As they gazed at the mountains, they were likely unaware that for almost six more months they would continue to gaze at the very same mountains. Because, for almost six more months, Noah's household would still be waiting on the ark— waiting in obedience, until God told them to leave the ark (Genesis 8:15).
