"You know that's wrong!"
What do we really know is wrong? Look at the people around you as you read this. Two out of three of the people you see do not believe that moral truth is absolute. Are you one of them? Someone might respond, "Of course I believe in absolute truth. I'm a Christian." Yet, fewer than half of Christians believe in absolute moral truth.
Are the days where we can say, "You know that's wrong" and expect that people will agree, in the past? More practically, will you conform your thinking to the current world views instead of to the view of God? Paul wrote to the Galatians regarding some things that are obviously wrong. He said the works of the flesh or sinful nature are plain, "Sexual immorality, impurity and debauchery (unbridled lust and shamelessness); idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like" (Galatians 5:19-21).
These sins that spring from the wickedness inside the human heart will always be wrong. Christians are called to remember the shame and death that actions and attitudes like these brought to our lives and remain committed to resist the temptations to return to old ways of living. That's Life at Work!
