Read 2Corinthians 6:11 - 7:1 with genesis 6:1-12
What was one of the grave mitigating factors in the decline of mankind into such depth of sinfulness that God determined to bring the great flood to destroy the earth? It was the decline away from God by his people. While we recognize the church was not formally called such until the time of Christ, in the Old Testament, the seeds and beginnings of the church are drawn out by those called his people. Here the church is seen in the line of Seth - the sons of God, and that line of God’s people severley declined by Noah’s time.
