There's a saying in the akan language that goes like, "Biribi ni wiase aa, anka y3da.. y3nto pono mu", which translates as if there world was just as it was, perfect with no evil etc then there wouldn't have been the need to sleep and lock the door.
The world is surely not all our eyes can see and so we have to be on guard and do the needful always that we may not fall prey to these spiritual attacks. Thanks for sharing this with us
