{This} (haut(885c)) {--that} (hina). Explanatory use of hina
with haut(885c), as in  Joh 17:3 , to show what "the love of God"
( 4:9,12 ) in the objective sense is, not mere declamatory
boasting ( 4:20 ), but obedience to God's commands, "that we keep
on keeping (present active subjunctive as in  2:3 ) his
commandments." This is the supreme test. {Are not grievous}
(areiai ouk eisin). "Not heavy," the adjective in  Mt 23:4 
with phortia (burdens), with lupoi (wolves) in  Ac 20:29 , of
Paul's letters in  2Co 10:10 , of the charges against Paul in  Ac
25:7 . Love for God lightens his commands.
