This guy at, Bible Flock Box, is just one of the many reasons myriads are being led astray when it comes to Scripture ... He's apparently a Seventh Day Adventist who doesn't get that once we have accepted the God of Abraham, Isaac and Jacob, we MUST do exactly as HIS people do. (Numbers 15:13-16)
Since we are ONE in Messiah (Gal. 3:28, Rom. 12:15), why would there be differences between YHWH's natural and adopted children? Does He EVER suggest that "Gentiles" would have different rules? WHY would they? Once a "Gentile" crosses over spiritually, they're no longer "Gentiles" - they are HEBREWS!
People, please don’t be misled by this guy. He does NOT understand Scripture!
