Hello Guys,

Christianity is strongly based towards the right hand. It is the right had that gives the blessing and make the sign of the cross.
On one count, the bible contains over 100 favourable reference to the right-hand and 25 unfavourable references to the left-hand. E.g.: The right hand of the lord doeth valiantly, the right hand of the lord is exalted (Psalm 118 vv15,16)
The left hand does worst in the parable of the sheep and goats. The sheep are set on Christ's right hand and the goats on the left. Those on the right inherit the kingdom of god while those on the left depart into everlasting fire (to quote Matthew 25: verse 41: Then he will say unto those on the left hand, ‘Depart from me, you cursed, into the eternal fire prepared for the devil and his angels.”)
The situation is much the same in Judaism and Islam. In Islam, the left hand and everything associated with it is seen as unclean. This stems from the Middle Eastern custom of using the left-hand and water instead of toilet paper and, more recently, of using the left handed to hold toilet paper for the same function. This is the origin of the term “cack-handed“

Thanks

I didn't find the right solution from the internet.
