{I have written} (egrapsa). Repeated three times.
Epistolary aorist referring to this Epistle, not to a previous
Epistle. Law (_Tests of Life_, p. 309) suggests that John was
interrupted at the close of verse  13  and resumes here in verse
 14  with a reference to what he had previously written in verse
 13 . But that is needless ingenuity. It is quite in John's style
to repeat himself with slight variations. {The Father} (	on
patera). The heavenly Father as all of God's children should
come to know him. He repeats from verse  13  what he said to
"fathers." To the young men he adds ischuroi (strong) and the
word of God abiding in them. That is what makes them powerful
(ischuroi) and able to gain the victory over the evil one.
