If a single verse catches the essence of Noah’s character and the quality of his relationship with God, this is it. Even if we consider only a general overview of his lengthy life, this verse provides an extensive amount to ponder.
Though the verse offers no details, it suggests how he dealt with the times and carrying out his tremendous responsibilities. It is not intended to imply that he was absolutely perfect in his conduct at all times and under every circumstance. Considering the times he lived in, his life was undoubtedly tumultuously stressful, yet he obeyed God.
He certainly was not of the stature of Jesus Christ. The verse, though, is intended to convey an essential truth: Noah was an unusual and distinctively godly person, one among billions. In short, he was humble before God and faithful, dependable in carrying out his responsibilities. He could be trusted.
The wording indicates that he did not deviate from what God charged him to do. He did not add his own thoughts about God’s commands in a sort of “here is the way I see it” manner. He humbly did as God instructed him despite the social pressures against him, and what he accomplished he did with determined class.
