{Love} (h(8820)agap(885c)). The love just mentioned. {That we should
walk} (hina peripat(936d)en). Object clause in nominative case in
apposition with agap(885c), with hina and the present active
subjunctive of peripate(935c), "that we keep on walking." {The
commandment} (h(8820)entol(885c)). The one just mentioned with the same
construction with hina as in  1Jo 3:23 . John changes from the
first person plural to the second ((886b)ousate as in  1Jo 2:7 ,
peripat(8874)e) as in  1Jo 2:5,7 . {In it} (en aut(8869)). Either to
al(8874)hei(8369) (truth) of verse  4 , agap(885c) of this verse, or
entol(885c) of this verse. Either makes good sense, probably "in
love." With peripate(935c) (walk) we have often en ( 1Jo 1:7,11 ,
etc.) or kata (according to) as in  Mr 7:5  1Co 3:3  2Co 10:2 ,
etc.
