As for prayer, Father Amorth of Rome suggests this
"O Father, come and visit
our home (shop, office,
and so forth) and protect us from the lures of the
enemy; may Your holy angels come to guard
peace and may your blessing remain with us
forever. In Christ Our Lord, Amen.
"Lord Jesus Christ, Who
said to Your apostles, 'In
whatever home you enter, greet it, saying, 'Peace
be in this home,' let this same peace,
abide in this place. We beseech You to sanctify it
by the merits of our trusting prayer!
blessings on it, and make it a place of
peace. May salvation enter our abode as it entered
the house of Zacchaeus,
when You graced it with
"Entrust Your angels to guard it and banish from
it every evil power.
"Grant that all who live in it may please You with
their good works, and so receive from You, when
comes, the reward of Your heavenly
home. We ask this through Christ, Our Lord, Amen."
Once we rid evil, we experience
a new joy -- and
the realization, says Father Amorth, "that
whenever God allows evil to happen, it is always
a greater good."
