The practice has proved that the highest stage of love is selfless, and this can occur both between individuals and between foreigner.
Communication between people is both verbal and nonverbal, and studies have proven that Speech is a small percentage of interpersonal communication. They also say that: a picture is worth a thousand words, and a thought a thousand pictures. Marital love may not be the highest communication because in very few cases people having love means that really love their partners so .....
Faith, however, is another story. Faith can not enter into certain patterns, everyone sees faith with other eyes. But whatever the point of view of everyone, faith is beyond what we see and feel physically, beyond matter. And I do not see how marital love can go beyond the limitations of the flesh, matter.
In history there have been millions of martyrs for their faith, a faith different from the majority or the occupation forces. Millions of people have preferred to lose everything, including life, in the name of faith, a supreme ideal. Stefan Apostle said, "I see heaven open and the Son of God ......". But how to get people to believe something you do not see? How can we trust completely in an illusion? Probably illusion is not an illusion, for man to communicate with God in prayer and communication involves a relationship.
So. Faith with selflessness is the deepest form of communication.
