And when the Scribes and Pharisees saw him eat with publicans and sinners, they said unto his disciples, How is it that he eats and drinks with publicans and sinners? -
Mar 2:16 In this passage Jesus is judged yo be a Sinner because He associated with Sinners.
Now we know the purpose for which Jesus associated with them. He came to Seek and Save that which was Lost.
He didn't associate with Sinners to condone their Sin. Neither did He associate with them to enjoy their Sin. And He certainly did not associate with them to learm how to Sin like they did.
So, in all of our relations with people we must consider our purpose and the implications of that association in the eyes of others with respect to our TestimonyOfJesusChrist.
