{And} (kai). Mutual fellowship depends on mutual knowledge
(Westcott). {Message} (aggelia). Old word (from aggelos,
messenger), in N.T. only here and  3:11 , and note ap' autou
(from God like apaggell(935c) in verse  3 ) and anaggellomen, to
announce, to disclose, here as in  Joh 4:25 . {God is light} (ho
theos ph(9373) estin). Precisely so the Logos is light ( Joh
1:4-9 ) and what Jesus claimed to be ( Joh 8:12 ). John repeats
it in negative form as he often does ( Joh 1:3 ).
