If you are a child of God, a follower of Christ, you must be set apart. What the world does you can not follow. You are to consecrate yourself to the holiness and righteousness of Christ. It will be worth it in the end.
1 Peter 2:9-12 AMP
“But you are a chosen race, a royal priesthood, a consecrated nation, a [special] people for God’s own possession, so that you may proclaim the excellencies [the wonderful deeds and virtues and perfections] of Him who called you out of darkness into His marvelous light. Once you were not a people [at all], but now you are God’s people; once you had not received mercy, but now you have received mercy. Beloved, I urge you as aliens and strangers [in this world] to abstain from the sensual urges [those dishonorable desires] that wage war against the soul. Keep your behavior excellent among the [unsaved] Gentiles [conduct yourself honorably, with graciousness and integrity], so that for whatever reason they may slander you as evildoers, yet by observing your good deeds they may [instead come to] glorify God in the day of visitation [when He looks upon them with mercy].”
