Crucifix or icon in EVERY room. My room makes up for the lack in other rooms, but tis my older sister's place, I do not have the authority to dictate on many matters. So I keep myself as covered as I can be.
There is so much evil that happens now outside of one's home, extra precautions in this spiritual combat must be taken, as I have listened and read from exorcists.
Yes, I have a blessed Crucifix in my bookshelf right next to my bed with blessed icons of Ss. Augustine, Monica, John of the Cross and Margaret Mary and blessed statues of Our Lady of Fatima and St. Michael flanking the Crucifix. There's an icon of Our Lady in my son's room and I need to dig out another one to be blessed to put in the girls' room as well. Once my in-laws move out, I'm getting two nice pictures of the Sacred Heart of Jesus and Immaculate Heart of Mary for our living area, regardless of what my wife thinks, and renewing the home Consecration to the Sacred Heart of Jesus, which I made a point of doing last Sunday after Mass.
Come to think of it, I have a couple small blessed St. Benedict Crucifixes still up on the outer doorways of my old house that I'll probably remove and put up at the new house too.
Already one positive note is that my 5-year old daughter convinced my mother-in-law to test her memory and recite bedtime prayers with her.
