{Message} (aggelia). In N.T. only here and  1:5 , but
epaggelia (promise) fifty-one times. {From the beginning} (ap'
arch(8873)). See  1:1  for this phrase and  2:7  for the idea. They
had the message of love for the brotherhood from the beginning of
the gospel and it goes back to the time of Cain and Abel (verse
 12 ). {That we should love one another} (hina agap(936d)en
all(886c)ous). Sub-final clause (content of the aggelia) with
hina and present active subjunctive. John repeats the message
of  2:7f .
