Noah accomplished a significant witness, persevering for a very long time under horrific conditions. His witness was of sterling quality and worthy of emulation.
These two verses appear quite innocuous. We read them and consider their teaching a matter of course regarding Christian life and salvation. However, for this world's Christianity, they pose a dilemma for those more deeply aware of the intricacies of Christian responsibility.
Calvinist theologian Arthur Pink (1886-1952) says in his exposition of this passage, "The verses which are now to engage our attention are by no means free of difficulty, especially unto those who have sat under a ministry which has failed to preserve the balance between Divine grace and Divine righteousness." Why would he say this? These two verses, almost single-handedly, nearly destroy one of the most treasured teachings of this world's Christianity—the Doctrine of Eternal Security, the "once saved, always saved" or "no works required" doctrine.
Note the end of the quotation: Some ministries have "failed to preserve the balance between Divine grace and Divine righteousness." Preachers who fail to maintain this balance strongly emphasize God's favor while neglecting or ignoring His claims on our lives—our duties and responsibilities to Him—because He owns us! We are His slaves!
To any thinking person, these verses severely undercut those preachers' claims that appear to guarantee grace, that is, to assure salvation. How? Verse 6 clearly states that God rewards those who live by faith, and verse 7 illustrates that, in Noah's case, the reward was that Noah and his house were saved because of what they did.
What did Noah do that was so important to his and his family's salvation? His works produced the ark, the means of escaping death from the Flood. Noah's works were rewarded. Where, then, is grace?
Note that I wrote that these verses "nearly destroy" this concept, not "totally destroy." They do not contain the entire story, but they are very troublesome, to say the least, to those of the no-works stripe. If they do not bother a nominal Christian, he is clearly ignoring what the verses really say, that a person's works play a large part in his salvation. What would have happened to Noah and his family had they convinced themselves that, since God had given Noah grace, no ark needed to be built because God would save them anyway?
