"With friends like that I don't need any enemies."
Personally, I would forgive them (meaning I would not seek any revenge, and would not exact 'what they owe', but would turn it over to God). I would pray for God to help manage my affairs with a godly, Christ-honouring temperament.
And my future relationship with that person would be based upon the knowledge that they 1)are quick to seek governmental intrusion and possible destruction of my family unit, and 2)are quick to gossip, and therefore 3)are anything BUT 'friends' with me or my family.
I hold no grudges against snakes (vipers) but if they show up on my porch or near to my house they are dead meat. Nothing personal, I just know what they are capable of and I make a rational decision to protect my family and home. Same thing with people, when people prove who they are and what they do by their actions, you need to take those things into account when dealing with them in the future.
'Fool me once, shame on you, fool me twice, shame on me.'
He that is void of wisdom despiseth his neighbour: but a man of understanding holdeth his peace.
(
Proverbs 11:12)
A person of understanding is not going to go about as a tale-bearer, destroying their neighbor's reputation or bringing an unfounded reproach upon them. So then, according to the Bible, someone who does such a thing is 'void of understanding' and 'despises his neighbor'. Should you maintain company and closeness with someone who is void of understanding and who despises you?
He that troubleth his own house shall inherit the wind: and the fool shall be servant to the wise of heart.
(
Proverbs 11:29)
Don't trouble your own house, it brings bad ju-ju.
