Noah did not have sophisticated tools to help with decision making. He just relied on the good common sense God gave him. After the flood, he sent out a dove until it brought back a fresh olive leaf. He waited patiently until the time was right and then came out of the ark.
Throughout this amazing accomplishment of Noah, he simply followed what God told him to do. There wasn’t anything amazing about Noah; in fact, no one listened to him except his own family.
Many amazing accomplishments are a result of just plain good common sense; knowing that it is God that does the amazing part. Here’s a video that brings out this thought: Don’t ask me how I Know – Bobby Pinson.
If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you. – James 1:5
