James is full of practical and pastoral challenges to the emerging New Testament church.  Earlier in chapter 3 those who teach have just been warned about the dangers of the tool of their trade:  the tongue.  Now James lays out tests to see who may be genuine vs false teachers.  (… much like in Matthew 7:15-20 where Jesus discusses genuine vs false prophets.)  v. 13 – Is your wisdom being shown by your deeds?  v. 14 – Are you motivated out of self-interest or rivalry?  v. 15 – What characterizes your wisdom?  v. 16 – What are the results of your wisdom?  Our goal is that our wisdom be from above (Christ given and Christ-like) and be evident in our behavior and demeanor.
