I Know

I know my position on church membership seems at odds being as I don't believe any person should be cast out for any reason.

But it is in no way at odds. God is well able to keep peace in His field in spite of the tares. It is the caster outers I try and avoid. God being the head knows all hearts and I don't believe would put a closet gay in a teaching position ...but they might be in the building.
Joh 6:37

(ASV) All that which the Father giveth me shall come unto me; and him that cometh to me I will in no wise cast out.

Besides the enemy has to be in your presence to see your cup overflow. He can not disrupt that cup however.
