Jay, if your brother-in-law and sister talk and live as we do, then they too are the Lord's. We'd love to meet them.
Your supposition is likely wrong, however, because you're spiritually deaf and blind, unable to distinguish between true and false. And worse than that, you're bitter and unrepentant, looking to link us to those against whom you hold a grudge, so besides giving us an unsupported and ignorant opinion, it's also a tainted and corrupt one.
You're a liar, Jay, a dupe of Satan and his false love
, which fuels your venomous fangs. But now you've come to the Stone of Stumbling. This is your day of exposure and judgment, yes, very sad for you, but glorious for the Kingdom of God.
Paul and Victor
