you don't fear but do you dare to try the below which i
extracted from other forum :
my christian fren... used to brush
7th month off...
until got once... he stepped on offerings....
he reach home... sleep next day wake up... foot rot for next 2-3
weeks with foul smell and pus....
until he go back to the spot he stepped on and apologize then did
his foot heal...
from then he learned to respect such things...
he's still a christian tho...

I stepped on it accidentally for many times nothing happened.
Why i step on it?
u blame those ppl who do the offering. They put at road side and
the grassy areas, no wonder we step on it accidentally.
I respect other ppl's beliefs so i wont go and step on it
intentionally but sometimes i do step on it accidentally.
If i step on it accidentally i pray to God for protection. If
God is for me, who can be against me.
