2 Now the springs of the deep and the floodgates of the heavens had been closed, and the rain had stopped falling from the sky. 3 The water receded steadily from the earth. At the end of the hundred and fifty days the water had gone down, 4 and on the seventeenth day of the seventh month the ark came to rest on the mountains of Ararat. 5 The waters continued to recede until the tenth month, and on the first day of the tenth month the tops of the mountains became visible. Genesis 8:2-5
Even though it has stopped raining, Noah knew it wasn’t safe to go outside just yet even though he and his family were going stir crazy taking care of all the animals and not being able to breath fresh air.
Scholars estimate he built the ark for over 55 years with little sign of rain or disaster. Another month or two of waiting was not going to hurt. I suppose he didn’t have a lot of time to dream and wonder while on the art, but you can guess he had doubts about what it would be like with nobody around anymore. Any friends he had were gone. Everything built over history were gone, wiped out. He and his family had to start afresh, from scratch. Obviously God had brought them to this point, He’d certainly teach them all they had to know to survive in the new environment they would be entering. Still, they had to tend to hundreds if not thousands of animals in the interim.
Sometimes we get worried and flustered about things we cannot control. If God is moving you to do something, He will supply you with the “tools” and wherewithal to accomplish it. You will be more than adequate to accomplish it.
