{He first} (autos pr(9374)os). Note pr(9374)os (nominative), not
pr(9374)on, as in  Joh 20:4,8 . God loved us {before} we loved him
( Joh 3:16 ). Our love is in response to his love for us.
Agap(936d)en is indicative (we love), not subjunctive (let us love)
of the same form. There is no object expressed here.
