James 2:8-10

MLV(i) 8 Nevertheless, if you complete the royal law, according to the Scripture, ‘You will love your neighbor like yourself,’you are doing well. 9 But if you have shown-favoritism, you are working sin, being convicted by the law as transgressors.
10 For who ever will be keeping the whole law and yet will trip in one point, he has become liable to all of it.
