Through selfishness, people are in eternal conflict while through charity
they will be at peace.
If charity alone constitutes the basis of human institutions, people’s
happiness in this world will be guaranteed. According to Christ words,
only charity will also guarantee future happiness, since all virtues which
can lead people to perfection are implicitly contained in it. There will be
no room for selfishness, vanity, hate, jealousy and slander with the true
charity that was taught and practiced by Christ, nor for strong
attachment to this world’s goods. For this reason, Christian Spiritism
exhorts the maxim: WITHOUT CHARITY THERE IS NO SALVATION!
