v.2: what sets Christians apart (or should do at least)
v.6-8: some false teaching going on, which is why John wrote this
v.9: good to remember this when being taught
v.10: making God out to be a liar - how should we feel about this & react?
v.14: pray by His will
v.16-17: should pray for each other to 'beat' sin
v.21: interesting how so little space is given to this here?
