A PASSION TO COMMUNICATE: ENGAGEFULNESS! "Doer... Do What?"

Believers in Christ are called to teach! The Law of Activity... Engagefulness!  Be doers of the Word!  2 Peter 1:3-11 is our call to make our calling and election in Christ SURE... CERTAIN... CONFIDENT!  We will be sure when we DO THE WORD!  But what exactly does Peter define that we should be doing?  Do what?
