Three doctors were on their way to a convention when they had a flat tire. The first doctor said, "I think we've got a flat." After they got out of the car, the second doctor said, "It sure looks flat to me." The third doctor knelt down and said, 'It feels flat to me." Then nodding in agreement, they said, "We better run some tests."
The Bible clearly teaches that certain actions are sinful, yet man often is not willing to call sin "sin." He rationalizes behavior; he ascribes certain behaviors to societal evolution; and he excuses other behaviors due to the pressures of our culture.
We need to recognize that when the Bible calls behavior "sin," it is sin.
