​We have different standards inside the church.

Scripture:
What business is it of mine to judge those outside the church? Are you not to judge those inside? God will judge those outside. “Expel the wicked person from among you.”
1 Corinthians 5:12-13 NIV

Application:
Let's not be surprised to see worldly people crossing all types of lines of decency and being totally confused about even the most basic of things. Pity then, pray for them, and be available to counsel them in ways that don't compromise God's Word. But leave judgment of them to God. 
Inside the church, we have standards of decency that are not based on fads or human tradition, but God's Word. We should help those within our family. We share their faith and burdens. But if someone among us tries to bring in the world's standards of decency (or lack thereof), they need to be corrected. Be careful, though, because as we judge others, we too will be judged.

Prayer:
Christ Jesus, heal these troubled people of the world, and if there's a purpose you have for us to be part of the healing, equip us. Within Your church, please bring love and correction so that we may be sanctified for You. Amen.
