"Let every soul be subject to the governing authorities. For there is no authority except from God, and the authorities that exist are appointed by God. 2Therefore whoever resists the authority resists the ordinance of God, and those who resist will [a]bring judgment on themselves....
For he is God’s minister to you for good. But if you do evil, be afraid; for he does not bear the sword in vain; for he is God’s minister, an avenger to execute wrath on him who practices evil". - Rom. 13:
Jehovah's Witnesses live a life in rebellion to authority. They rebel first and foremost against Jesus when they mock his sacrifice every memorial by disobeying his command to eat and drink "for the forgiveness of sins" (Mt. 26: 27-28)
Then, they rebel against their own government that God has allowed at this time when it suits their whims.
Although they dress up the outside of the product, the reality is that JW's live a life in near total rebellion against God and their fellow-man. "They bind up heavy loads on others". For these and other reasons, they are almost impossible to get along with.
Jesus called people like this white-washed tombs.
