Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will. Romans 12:2
There is a term called being 'desensitized' to sin. You may be immersed in a particular culture or mindset for such a long time or have exposed yourself to so much, that it becomes difficult to distinguish evil.
Recently I viewed a movie which was a very romantic chick flick and fairly clean, some innuendos, but come to find out an underlying subtle message was in this film, that being assisted suicide was compassionate and perfectly okay and a person had the 'right' to end his life. This message was masked until the end of movie. Maybe the producers were hoping that by being immersed in the love story you would not think the underlying plot was so terrible.
We live in this world but we are to be set apart and separated from culture. Culture says men can marry men, babies that are inconvenient can be killed, a person who feels trapped in a body as a man can have sex change surgery, people who want to kill us have a right to live here and add to this list. We hear these things in the news so much we end up numb to evil. We are to love but we are also to run from evil and embrace the truth. The truth is found in the Bible. Read it daily to give you strength to face this opposing world view.
PRAYER: Give me discernment Lord when the world is tossing all kinds of false messages out there. Help me recognize the truth. In Jesus' name. Amen.
