Even if we know porn is
evil, it's another thing to resist it.
The first half of verse 3 above
suggests how: Find a physical reminder of the danger,
and post it prominently near the computer.
Maybe some verses
(check
out the rest of chapter 7)
stuck on the edge of your monitor. Maybe phone numbers
of friends you can call when temptation rears its
head.
Maybe a warning taped to your
virtual fingers the buttons on your
mouse.
Find something.
