We are in the world, BUT not of it -  New creations in Christ Jesus and - now citizens of heaven.

 

Isaiah 52:11
Depart! Depart! Go out from there, Touch no unclean thing; Go out from the midst of her, Be clean, You who bear the vessels of the LORD.

Numbers 16:26
And he warned the congregation, "Move away now from the tents of these wicked men. Do not touch anything that belongs to them, or you will be swept away because of all their sins."


Revelation 18:4
Then I heard another voice from heaven say: "Come out of her, my people, so that you will not share in her sins or contract any of her plagues.


Therefore, "Come out from them (the ungodly world system) and be separate, says THE LORD. Touch no unclean thing, and I will receive you."

Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, "perfecting" holiness in the fear of God. (2 Corinthians 6:17,7:1)
