To start off, faith is something personal. Its so personal that if I was to rate it to show how personal it is out of 10, I would give it a 15. Due to that fact, one should never try to change one’s beliefs or act condescendingly towards another because of their beliefs. Instead, those who have similar beliefs should come together once in a while and brainstorm on how to handle some of the ‘situations’ they encounter in their lives, after all, no man is an island. This way one gets to grow spiritually.
What exactly is growing spiritually?
Well, a human being has different facets; physical, mental, emotional/social, and spiritual which once developed individually make a complete human being. the spiritual dimension is often ignored by physiologists, economists, physicians and the rest of the math and science people. Don’t forget the computer guys too. Spirituality is related to your capability to discern between the good and evil, beautiful and ugly, your relationship with your god and transcendence.
To be spiritual, you don’t have to be religious, though there must be something that feeds your spirituality. Some use music, contemplative thinking, exemplary biographies, the environment, etc, but the simplest spirituality is attained by means of religious experience.
Those who are spiritually developed are usually more happy, relaxed and carry a certain atmosphere of maturity with them.
So whatever you use to feed your spirituality is up to you as an adult, nobody should give a damn, though you should check yourself not to become an antisocial because again, no man is an island.
Finally, faith is something personal even the bible shows that in Mathew 6:6,
“when you pray, go into your room and shut the door and pray to your father who is in secret; and your father who sees in secret will reward you.”
