One of the important lessons we learn from the life of Noah, is to obey purely by faith.
Hebrews 11 is a record of men and women known for their exceptional, yet imitable, faith. Verse 38 says that these individuals were worth more than earth deserved, and the reason for such a lofty commendation was simply because their faith was the most striking thing about them.
Noah is on this list in v. 7
By faith Noah, being warned by God concerning events as yet unseen, in reverent fear constructed an ark for the saving of his household. By this he condemned the world and became an heir of the righteousness that comes by faith.
Faith in God meets Fear of God. It is through faith, that Noah believed God. And it is in fear, that Noah obeyed God.
God didn’t twist Noah’s arm to believe the promise of a world-wide flood. God didn’t send the Noahic weather bureau a scientific analysis of the coming weather phenomenon. God simply told Noah it would happen. God simply came to Noah with the full set of plans, told him what would happen, and instructed him to build a floating vessel that could easily withstand 30m waves.
Being a man of faith, with a healthy fear of the Lord, Noah responded appropriately to God as His Lord. When God spoke no matter what He would say, Noah would obey. The Fear of the LORD enabled Noah to obey purely by faith. Noah knew that human rationale and time to consider were redundant if God speaks.
Genesis 6:13-21 is God’s first conversation with Noah. It includes the initial warning of the flood and all the instructions for building the ark. Verse 22 is the only verse dedicated to the actual building of the ark.
Noah did this; he did all that God commanded him.
About 100 years are included in v. 22! For a man who fears the LORD, the time required to obey perfectly is inconsequential. Hundred years of obedience were necessary for this one short verse to be in Scripture. Thousands of years later, we know the end of the story. We know God was right, and therefore it is a good thing Noah obeyed.
The Fear of God produces true obedience based purely on faith in God. If God said it, then it is the right thing to do, so I’ll do it.
