I think that over time, this will happen. now, almost a year after being recieved into the Church, all I can read when I "read for fun" are spiritual books. also, most of the music on my mp3 music player is Orthodox music (Church hymns) that I get from CD's from Church.
also, I find that I can no longer watch movies with a whole lot of things that would ignite the passions. I have sinply lost interest (and I used to be quite a big occult TV and movie junkie.)
as for websites, I have downloaded an Orthodox toolbar that I found from an old post on here (just search for it). whenever I log on, I use the little music player and listen to Ancient Faith radio. this keeps my mind on prayerful things when I'm on the net.
