Partiality, God, Gospel, and the Church

James 2:1-7

James makes an inseparable connection between the Lord Jesus Christ and those who are His followers.  Specifically, because Jesus did not show partiality (favoritism), therefore His followers [Christians] are not to show partiality (favoritism).
I can't rightly call myself a Christian and disdain, discriminate against, certain groups or persons.  

But wait a minute! Not so fast! Are we so sure Jesus didn't show partiality ?
