Why are we surprised when unbelievers act like, well, unbelievers? What would we expect? Writing to the Ephesians, Paul outlines the problem clearly just as he did in writing to the Romans:

Now this I say and testify in the Lord, that you must no longer walk as the Gentiles do, in the futility of their minds. They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart. They have become callous and have given themselves up to sensuality, greedy to practice every kind of impurity. (Ephesians 4.17 – 19, ESV)

As in Romans 1, the downturn begins with their attitude about God. Throw away God, and we get everything, including a society whose official position is that we don’t know what a “man” or “woman” is. I don’t know that we’ve changed much from Noah’s day except that God has a people demonstrating a different way of life – more on that tomorrow.

Then the LORD saw that the wickedness of man was great in the earth, and that every intent of the thoughts of his heart was only evil continually. (Genesis 6.5, NKJV)
