“Hebrews 11:7 says that Noah’s faith condemned the world. Christians are sometimes encouraged by statements like this to make it their job to condemn the world; they make it their ministry to point out how rotten it is, to fixate on the reigning sins and unite in hysteria over the latest debaucheries. But that does not seem to be the way Noah lived; he charted a different course for us.
Everything Noah did was calculated to save. He acted as an instrument of salvation, even though his faith indirectly condemned the world. He was an ambassador of the grace of God, and that is what every Christian is called to be.
Noah was a ‘herald of righteousness’ (2 Peter 2:5). Surely that involved a condemnation of sin and a warning of judgment, but all of that was done in the shadow of the ark of salvation. That is where Noah’s real effort went. His faith set him to work on the ark. If the world would not seek its open door, then yes, it would be destroyed. But Noah directed his labor to salvation. Our labor must have this same influence: to commend and offer salvation to others, praying that God will grant them faith to believe and be saved. This is the labor of the Christian, by faith in the Word of God. Paul said this in 2 Corinthians 5:19-20: ‘In Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation. Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on behalf of Christ, be reconciled to God.’
Believe, God says to the world through our faith, that a judgment is yet to come. And believe that in the cross of Christ—an ark as wide and long and high and deep as Noah’s ever was—everyone who believes will find safety through the storm” (Richard Phillips, Hebrews, 433-434).
