Transformation not conformation.

Transformation into Christ.
And not conformation into the image of worldly celebrities, or worldly patterns.

They shouldn't change you.
You should influence them, if you can.

You will be judged for not speaking the truth.

Presenting your bodies a living holy sacrifice is a service that God is in very need of.

Don't listen to the teaching of whatever you do with your body doesn't affect your spirit.
God said your body should be kept pure for Him.
And any one who defiles it , will be destroyed.

Pull down the strongholds the works of the flesh have over you by what Christ done for mankind on the Cross, and prayers, with right fellowshipping.
Evil association corrupts good manners.
( A little leaven leavens the lump.)

Romans 12 : 1 - 2.
