OK, I'll give it a go:
1. Those who practice it have genuine love among themselves
The "genuine" is a classic jw weasel word, implying that any love in the "worldly" world is fake. Ask them to define "genuine" vs "non-genuine" love and how to identify it.
2. (I'll leave to @Vanderhoven7)
3. They pray for God to sanctify his name
And so do all Christians who use the Lord's Prayer. They just don't incorrectly call that name "Jehovah".
4. They proclaim God’s kingdom in all the earth
Many Christian churches have missionaries and evangelists. Nor is the jw "coverage" in any way complete, or likely to be so "soon".
5. They keep separate from the world’s affairs
Not exactly. They accept pensions, health benefits and other allowances wherever they can. There's nothing creditable about taking and sneering at the giver.
6. They cultivate the fruitage of God’s spirit
Whatever that may mean. I think it means expelling (disfellowshipping) any deemed to fall short; so much for "genuine" love! Also, once again they cannot define exactly how they do this "better" than other denominations.
7. They obey all human laws not contrary to God’s law
And other denomination do not? This is not a distinguishing mark. Worse, they have flagrantly disobeyed the Working With Children legislation in Victoria until called on it. Even now many go door to door without a WWC card.
So how do these "prove" that they are the One True Faith?
