Christian values are what make it possible to have a peaceful country even with a large variety of other cultures present. Jesus calls on us to forgive love and be kind to all beings.
Islam and Judaism by contrast say to kill the non believers. Atheism says to kill the enemy of the state. Only Christianity recognizes the inherent dignity of all beings.

Jesus calls on us to help the poor, cause even the least is divine and worthy of love and compassion. UK is mostly Muslim/atheist now as far as I know.
