It is the holy who have been given the gift of the Holy Ghost.The Holy Spirit does not make one holy.
He will not reside in a polluted temple.
Agreed.God wants us to be part of the human race so that we can reach others with the Gospel.
We have different ideas on "holy".Holiness people are separationist. They are so holy that they cannot mingle with lost sinners. Remember, Jesus ate with sinners, a Jewish no, no. Go have a beer with a lost sinner and tell him about Jesus.
As Jesus, holy as God is holy, walked with and for the sinners, so do we.
I won't however, take part in unholy pastimes with them.
