Some people live in active denial of the trends around them, oblivious to the spirit of the age and to all intimations of God’s coming wrath. They are dull by choice.
For example, the Lord Jesus criticized the Pharisees and Sadducees for failing to correctly interpret the “signs of the times”. They were skilled at predicting the weather and ordering their workdays accordingly, but blind to the fulfillment of Old Testament prophecy all around them. More evidence would not be given to them because they willfully ignored the signs they had already seen.
This is not that.
