Answer:
Because it requires us to make personal sacrifice to help other.
Step-by-step explanation:
Christian charism is a concept in Christianity that refers to a power given by the holy spirit for us to be used on our day to day life.
Humans are naturally a selfish creature. We have a huge tendency to think only about ourselves while sacrificing other people. Having the kindness to sacrifice our own comfort for others can be seen as a sign of holy spirit entering our life. It gave Christians the strength to overlook their own needs for the benefit of others who might need it more.
