When we make friends, we should make friends with people with high moral character and holy personality, because he can guide us to be good. If the object of our belief wants us to kill people and surpass the bottom, then believing in him is not only useless, but harmful. We must know, is the virtue of the object I believe in clean? Is he compassionate enough? Is his personality perfect? If he does, then such an object is worthy of our belief and conversion.
