“Blessed is the man who does not stand in the congregation of sinners…” (Psalm 1)
“It is our wisest and our safest course to stand at the farthest distance from sin; not to go near the house of the harlot, but to fly from all appearance of evil (Prov. 5:8, I Thess. 5:22). The best course to prevent falling into the pit is to keep at the greatest distance; he that will be so bold as to attempt to dance upon the brink of the pit, may find by woeful experience that it is a righteous thing with God that he should fall into the pit.” —Thomas Brooks
Lord Jesus Christ mixed with sinners (didn’t ignore them) but He didn’t meet them by visiting places of vice (in modern terms, whorehouse, pub and the like).
Christ the Lord met sinners in everyday public locations.
